The electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultraviolet light, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers of our sun. Gamma rays are used in medical science but they are oftenly used to produce images of our universe. If you would like to know more about the spectrum keep reading.
The electromagnetic spectrum is the organization of six diferent wavelengths. Each having their own use. The spectrum in order from longest to shortest wavelengths is: Radio waves, Microwaves, Infrared waves,
Visible light, Ultraviolet light, X-rays and Gamma rays. The most familiar forms of the spectrum are radio waves and light waves. The reason for that is, that we listen to the radio or use its waves more often than we think. For instance cell phones work off of radio waves.
Light waves are used more often than we think because with out light we wouldent posibly be able to see color on any thing, or we wouldent have photosynthisis which sunlight is used for. The term spectrum refers to light in general or the whole range of electromagnetic radiation. The electromagnetic field was found in the 19th centurie. It was founded by
James Clerk MAXWELL of Scotland and published in 1865. The field is described in two quantities the electric component E and the magnetic component B and both charge in space and time. This meaning electric / magnetic / spectrum.
Radio waves are used to transmit radio and television signals.
Radio waves can send sounds at the speed of light. The range of radio waves can be less than a centimeter to tens or even hundredths of meters.
Radio waves are produced by coherent motion of electrons such as the antenna of a radio transmitter. Coherent motion is the focused pattern of the waves, in this case. The radio waves are also produced by charged particles orbiting in magnetic fields. As you already know we have FM and
AM radio waves. Well an FM radio station at 100 on the radio dial (100 megahertz) would have a wavelength of about 400 meters. A radio wave can also be us...

Acknologements:
I would like to thank Mr. Rhan for giving me the time to work on the electromagnetic spectrum during his math class period. And I would also like to thank that stupid voice in my head for keeping me on task, against my will. I cant forget good old Mr. Garcia for giving me such a short time to finish this but the confidence it took to succeed as well. And my dear old dad since he asked me to thank him too.
In Kate Chopin’s story “The Storm” it talks about love and lust. It speaks of two kind of storm that occurs. These two storms I find to be the central part of the story, and is being represented as a symbol within the story. The first storm is the most obvious one that Bibi and Bobinot are faced with. The second storm isn’t that visible for it involves Calixta and Alcee. Just as like most storms they come and pass.
She calls him "old lecher/old liar", which means when he was alive the father often made empty promises of false hope about mending everything, but the family could no longer wait for him (Clifton 9, 10). She wishes that her father was rich, so he would have money to pay the mother when she asks for his salary on Friday; he would be able to repay the mother all she deserved being his wife. The impatient tone is still there, but it is more mellow. Rather than expecting her father to cough up the money like before, she now wishes that he has the money. This is the turning point. In addition, the daughter explains how her father has grew up in the same circumstances, "son of a needy father,/the father of a needy son" (Clifton 12,13). She admits that her father "gave … all he had" even though it was not much (Clifton
'The Storm' begins on a stormy spring day, with the protagonist Calixta at her sewing machine. She is alone, her husband Bobinot and son Bibi have gone to the store. Calixta seems to be a bored woman, confined to her duties as a housewife and mother. As the distant storm approaches she is unaware of what the storm brings, her former lover Alcee. Calixta allows Alcee into her home and opens her whole world to him. There is a connection between the storm that is going on outside and the storm of emotions going on in Calixta and Alcee. The weather sends Calixta into Alcee?s arms, he wraps his arms around her, and they can no longer hide their feelings for one another. They gave into their raging emotions and made love. Outside the weather was subsiding and Calixta and Alcee?s bodies felt relaxed and calmed. ?The rain was over; and the sun was turning the glistening green world into a palace of gems.? (1614) His face beamed with light like the sun. The storm inside of her was satisfied and for a brief instant Calixta felt liberated from her ordinary dull life.
The two literary texts that accurately expresses these communication problems are found in Columbus’s Letter on His First Voyage and The Divine Narcissus. The first text called Columbus’s Letter on His First Voyage is in the form of a letter written by Christopher Columbus to the Royal family of Spain,
The short story “The Storm” by Kate Chopin, deals with the subject of adultery. The story takes place in the early 1900’s. There are two main characters, Calixta (the wife) and Alcee (the former lover). Alcee must take refuge from a passing storm in Calixta’s house, while he is there the two end up making love while Calixta’s husband and son have to wait out the storm at the local store. By doing this Chopin implies the theme that is, adultery is natural and does not necessarily have negative consequences. Through out the story the constant changing of imagery plays a great role in the development of characters and their ability to demonstrate the theme.
For decades, the effects of radiation has been studied by doctors around the world. X-rays are used in the medical and dental field to take radiographs of certain parts of a person's body. Some have become concerned of the long term and short term effects of having x-rays taken because of the radiation that is exposed. Since the rise of concern, studies have been done to find any type of link between cancer and radiation from x-rays. Specifically, in dental x-rays, researchers have been performing studies trying to prove that radiation from x-rays in the dental office can cause cancer .
In 1998 a Maryland neurologist, Dr. Christopher Newman, was diagnosed with brain cancer and he could no longer work as a result of his disease. He claimed that the Motorola cell phone he had in 1992 to keep in touch with his patients gave him cancer. Then in 2000, he filed an $800 million lawsuit against several wireless providers including Motorola Inc., Verizon Communications Corp., Bell Atlantic Mobile Systems, and others. Within a month, the U.S. District Judge Catherine Blake dismissed the case due to lack of evidence. This case happened during a time where people were confused about how electromagnetic radiation affects the human body. Fast-forward to today and there is still confusion. A lot of people today feel like they are at risk from developing cancer from electronic devices like cell phones, microwaves, and laptops. That is simply not true.

In her short novel The Storm, Chopin explained how an extramarital affair between Calixta and Alcee became a factor benefiting the marriage. Chopin ended the story with the words, “So the storm passed, and everyone was happy” (123). The story is interesting not only because of the conclusion that infidelity had a beneficial short-term outcome to the family relationships, but also by intricacies that resulted in the happy end. In the middle of the novel, Chopin utiliz...

Kate Chopin's "The Storm", is a short story about a brief love affair that takes place during a storm that has separated Calixta with her husband and son. The title "The Storm" is an obvious reference to the storm outside, but more importantly to the love affair that takes place. The title refers to nature, which is symbolically used again and again in the story. Chopin uses words like "somber clouds", "threatening roar", and "sinister intentions" to describe the approaching storm. Later in the story those same words in reference to the storm outside, will also be represented symbolically to the storm brewing inside with the love affair. In the beginning of the story Bobinot and his son Bibi stay at a store to let the storm pass by. Calixta, the wife , is at home by herself doing some chores around the house. As the storm starts to approach, Alcee rides in and asks Calixta if he could come in until the storm passes. It starts to rain immediately after he arrives. It's important to know that Alcee and Calixta had past together which he brings up to her later in the story. It is also stated that she has never seen him alone. The storm starts to increase outside, reflecting the sexual tension inside. The storm's sinister intention appears when "The rain beat upon the shingled roof that threatened to break an entrance...". It seems that the storm knows what is going on between the two and is threatening to break in and ruin their chances. They move through out the house and end up in the bedroom "with its white, monumental bed, its closed shutters, looked dim and mysterious. The bed being white symbolizes purity. The two then make their way to the window to watch the storm outside when lightning strikes nearby, falling back into his arms. The storm in a sense seems to be forcing them together now. They then embrace each other in the peek of the storm where things really start to get stormy in the love affair. The two then start making out yahda, yahda, yahda. The thunder is now distant and passing away. The storm outside turns into a soft, lighter rain, being symbolic that the storm is ending.
Many short story writers have written about the gender and role of woman in society. Some of these stories express what Barbara Walter calls, “The Cult of True Womanhood” meaning the separation of both man and woman in social, political and economic spheres. In order to be considered a “true woman” woman were to abide by the set of standards that were given to her. Women were expected to live by the four main principal virtues - piety, purity, submissiveness, and domestication. In Kate Chopin’s short story, “The Storm,” Calixta the main female character breaks away from “The Cult of True Womanhood” when she has a sexual encounter with her past lover Alcée. The storm goes through many twists and turns that tie with their adulterous actions. Although she breaks away from the four main principal virtues, she in the end is considered to be pure innocent of heart because the action in which occurred happened instantly, and as white as she was, she was taken away from her innocence.
When a ray of light is bounced or reflected off of a plane surface, there is a specific law that can be used to predict the angle at which it is reflected off of the surface. This is known as the ‘Law of Reflection’ and it states:
