Many times people do not see what exactly light is. People overlook the actual definition of light: the natural agent that stimulates sight and makes things visible. Without light things would not show an appearance to us. Light is part of the electromagnetic spectrum. Light is detected by the human eye; therefore we overlook the science behind light.
The electromagnetic spectrum is what ranges from radio waves to gamma rays. It is also what shows the range of all possible frequencies of electromagnetic radiation. Parts of the spectrum include: Gamma rays, x-rays, infrared, and ultraviolet light. a wide range of wavelengths and photon energies is found by the electromagnetic spectrum. Everything that a human eye can “see” must have a wavelength about the same size as or smaller than the object. The wavelengths are what are viewed on the spectrum. From the human eye we use the visible spectrum which is a very small portion of the electromagnetic spectrum.
The smallest atom is the hydrogen atom which contains only one electron. Different waves inside of an atom describe where the electron is most likely to be found inside of the atom. The more waves, the more electrons that is located in the atom. Wave functions depend on the amount of energy of the atom. Electrons inside of an atom can range from a close to far distance from the nucleus. Normally we find the electron to be close to the nucleus. The distance of the electron from the nucleus depends on the amount of energy. Since all electrons are found around the nucleus energy is still quantized. The closer the electron is o the nucleus the lower the potential energy. Therefore there is a higher amount of potential energy when the electron is near the nucleus. Potential energy is t...

...depends on the amount of valence electrons that the atom has. Each will have different chemical properties. A noble gas atom will not react at all, and be chemically stable. A halogen atom (an atom with an electron missing), or alkaline metals will be very reactive unlike noble gases and will tend to form strong ionic bonds with other atoms. They will contain very high fusion points when the two atoms are combined with each other. The arrangement of electrons the way the atom will form chemical bonds.
Overall we are able to understand that all rolls of chemistry play a huge factor because in the long run many of them relate to each other. Even though we think that we understand what light is, after defining “light” and taking a closer look we can notice that it contains many smaller parts that link the reactions and behaviors of the electron inside of an element.
The electromagnetic spectrum is a range of different types of radiations, this is energy that travels and spreads out as it goes. This range involves more than just visible light- small portion of the spectrum detected by the human eye- it goes beyond what the human eye cannot see. The two most important characteristics of the spectrum are wavelength and frequency. The electromagnetic spectrum can be divided into three different parts: the theory of visible light, the range of the electromagnetic spectrum, and how it benefits mankind.
The atom is made up of mostly empty space, but it still has many parts (Doc. 2). At the center is a positively charged ball of mass called the nucleus. Inside the nucleus are protons and neutrons. Protons are positively charged particles, and neutrons are particles with no charge (Doc. 3). The nucleus is surrounded by a cloud full of electrons (Doc. 3). Electrons are negatively charged particles (Doc. 3). They move around the nucleus in discrete regions called energy levels (OI). Protons and neutrons can be broken down into quarks
The purpose of this lab was to analyse how light and color is created inside an atom in order to deduce what an unknown chemical compound was. We did two different experiments in order to examine how light is created and changed. In one, we looked at how chemical compounds affected a flame’s color, and to determine what the unknown salt contains. In the other lab, we looked at how atoms create light, and how it is displayed on the elements individual spectral line.
My book, “All The Light We Cannot See” by Anthony Doerr, talks about a blind girl who falls for a German soldier. The most exciting thing about this book is the setting and the characters. They are unique and creative. You should be interested in reading this book because it shows the importance that looks do not matter in love. If your love is so powerful and strong it can overcome through the hardest and difficult obstacles.
The spectrum of an object is the variation in the intensity of its radiation at different wavelengths.
For thousands of years humans have had conflicts ranging from the Hundred Years war to World War II. Every set of conflicts we have seen over the course of history has brought new challenges and obstacles for those trying to survive but there is one thing that has remained constant, we must become mentally and physically stronger if we want to see the light at the end of the tunnel. Throughout All the Light We Cannot See, Anthony Doerr proves that in times of conflict one must undergo change in order to survive.
The story that is most significant to me is “Reading the Light'; by Roger Pfingston. This story felt like it was written from the heart. It is filled with emotions, ones that the author caught in his story very well. Even though I could not empathize with Brian, I did feel sympathetic towards him. When David said to Brian, “Is it really such a surprise? I’m sure you know that your mother and I haven’t been the best of friends lately.'; (6), that was a shock to me. David did not seem to be sympathetic towards his son; instead he made it sound like it had happened and that there was nothing that could be done about it. At the end of the story, David, Maria and Brian went to the park where the author stated “The three of them stood huddled in the glare of ice and sun.'; (7) My heart sank. They just stood there accepting that their family was breaking up. I thought that Roger Pfingston wrote this story from his heart. I was able to put myself in Brian’s place and actually feel how I thought he would feel.
The model of the atom has been changed many times over the course of history, updating from a theory about cutting things in half to an atom with protons, neutrons and electrons.
We depend on electromagnetic energy every moment of our lives, from watching tv to microwaving our food, without it our world would not be the same. Electromagnetic energy travels in waves, and has a very large range from long radio waves to very short gamma rays called the electromagnetic spectrum. The electromagnetic spectrum is the distribution of electromagnetic radiation according to energy, frequency or wavelength. From radio waves to gamma rays there are 7 types of lights most not visible to the naked eye in the electromagnetic spectrum which covers a wide range of wavelengths and photon energies. Different objects and living thing detect different proportions of the spectrum, the human eye can only detect visible light, radios can detect a different portion of the spectrum, and an x-ray machine uses another portion. To study the universe NASA's uses a scientific instruments which can detect the full range of the electromagnetic spectrum.
Light is both part particle and part wave. Light is “the electromagnetic radiation that may be perceived by the human eye”. It consists of photons, which are massless bundles of concentrated electromagnetic energy. Light’s lower frequency is red, and the higher frequency is blue. Like sound, light has frequencies humans can’t detect. Ultraviolet light is at a frequency higher than violet, and infrared is at the frequency lower than the red of visible light. We get UV (ultraviolet) rays from the sun, and infrared is used in night vision to see better.
Energy is the ability to cause change. A type of energy is the powerful rays of the sun. The suns beams are Radiant energy when it hits Earth. Energy comes in different forms such as: heat and sound. When you see things it is reflected of your eyes. Light affects how we see things around us. Thomas Edison designed the first-long lasting incandescent light bulb in 1879. Light travels in waves and is emitted from a source. The sun gives of Visible and Ultraviolet light. Light waves have peaks and valleys. The peaks and valleys have wavelengths. It depends on the type of the light. There is light on an Electromagnetic spectrum and it has all types of different lights. The Electromagnetic spectrum has different types of rays. The sun emits different types of light. It gives of Infrared light, Visible light, and Ultraviolet light. The shortest wavelengths are: Gamma rays, X-rays, and Ultraviolet rays. The longest wavelengths are: Infrared rays, Radar, F...
characteristics. Degree of metallic character is related to an element’s ability to lose electrons while degree of nonmetallic character is related to an element’s ability to gain electrons. The final periodic trend, ionization energy, the energy required to remove an electron from an atom, generally increases when moving across the table from left to right and decreases when moving down the table. Because their valence shells are full, noble gases have very high ionization energies with the greatest ionization energy belonging to Helium.
As for the valence electrons, they are simply electrons that are shared when atoms bond together. Moreover, you can find the number of valence electrons an element has just by looking at the periodic tables. The number of valence electrons is the same as the atom's group number which can be found by looking at its column. For example, carbon is in group 4; therefore, it has 4 valence electrons. The elements of the periodic table can be divided into three categories; metals, nonmetals, and metalloids. The periodic table is mostly elements that are metals which are good conductors of heat, however nonmetals are not good conductors of heat, and metalloids have properties of both metals and nonmetals. The elements in the periodic table are divided into groups. Group 1 are the "Alkali Metals" and they're the first column in the periodic table however, excluding Hydrogen. The Alkali metals are so soft and very reactive metals. In addition, Group 2 the " Alkaline Earth metals " are listed in the second column of the periodic
The development of quantum mechanics in the 1920's and 1930's has revolutionized our understanding of the chemical bond. It has allowed chemists to advance from the simple picture that covalent and ionic bonding affords to a more complex model based on molecular orbital theory.
Electromagnetic radiation is energy that flows through free space. Electromagnetic radiation comes in a list of energies known as the electromagnetic spectrum. Electromagnetic spectrum is the complete range of the different wavelength of electromagnetic radiation. It consists of light, radio waves, visible light, infrared waves, ultraviolet light, x-rays, microwaves and gamma rays.
