The Electromagnetic Spectrum
The electromagnetic spectrum is the collective name for all types of
radiation. Radiation is energy that travels around in waves. The
electromagnetic spectrum goes from the waves with the lowest energy to
those with the highest energy.
Radio Waves

Radio waves have the longest wavelengths in the electromagnetic
spectrum. They can be from as long as a football to as long as a
football pitches. Radio waves carry signals from devices from one
place to another invisibly through the air.
Radio waves are used for many different jobs:
b In Medicine - radio waves are used to transmit the pattern of a
heartbeat through a monitor at a patient's home to a nearby hospital.
They are also used to radio the condition of a patient from an
ambulance to a hospital. Radio waves are used in medicine when
paramedics are dispatched to the scene where they are needed. The
hospital can tell the paramedics the condition of the person so that
the paramedics can prepare a medical treatment kit.
b In Industry - used mainly in the transportation business. Radio
waves can also be used to provide communication on construction sites.
b In Science - radio waves from outside the earth are detected using
in radio telescopes. Radio waves are picked up when they hit the
antenna of the radio telescope. The wave then goes to the tuner, then
to the amplifier, and finally to the plotter.
b For Consumer Goods - these waves are used in the remote control
models which people buy. They are also used in radios, televisions and
wireless headphones. The antennae on your television set receive the
signal, in the ...

the hottest regions of the universe. Things like supernova explosions
(the way massive stars die), neutron stars and pulsars, and black
holes are all sources of gamma rays.
Unlike optical light and X-rays, gamma rays cannot be captured and
reflected in mirrors. The high-energy photons would pass right through
such a device. So gamma ray astronomy took along time (in comparison
to other forms of astronomy) to develop.

If you could see gamma rays, the night sky would look strange and
unfamiliar.
This gamma ray moon picture just looks like a round blob - lunar
features are not visible. In high-energy gamma rays, the Moon is
actually brighter than the quiet Sun.
We are still discovering more about gamma rays and they are the most
unknown waves of the electronic spectrum.
A spectrum is a group of light wavelengths that are ordered in relation to their wavelength length. The electromagnetic spectrum consists radio waves, microwaves, infrared, visible, ultraviolet, X-rays and gamma rays. (1)Specifically, this lab looks at the visible light part of the spectrum because one of the colors in the visible light spectrum is shine through the sample. The visible light spectrum consists of colors of red, orange, yellow, green, blue, indigo, and violet. The color chosen to be shine through the sample is affected by the color of sample when mixed with the indicator Ammonium Vanadomolybdate (AMV). The color on the color wheel that is opposite of the solution’s color is the color that is shined through the
The task of interpreting William T. Vollmann’s works seems as monumental for the reader as writing the story oneself. The text of “The Visible Spectrum”, in fact, does not feature any extensively challenging vocabulary or particularly thwarting subject matter; yet it would seem that in all of its “objectivity” and “transparency”, there lies no obvious, dominant or intended interpretation. The narrative is ambiguous in its “message” to an infinite degree, and thus the reader must construct its “meaning” given only scraps of discontinuous plot, description and dialogue.
...nd violet wavelengths are the shortest, and violet is the least visible to the human eye. These wavelengths are scattered throughout the day and caused by a redirection of the light-waves direction due to gas molecules in the atmosphere (Mc Knight, p. 84). When the sun is setting towards the end of the day there are few blue wavelengths left and we see orange and red which are dominant and the longest wavelengths of visible light to the human eye. At the bottom of the photo (closest to the setting sun) red and orange are the dominant visible colors with the occasional blue and almost violet. If our eyes could not see orange and red our sunsets would be a dark blue or black.
In the French coastal town of Saint- Malo in August 1944, War World II is coming to its high point. The allies are landing and fighting against Germany. Anthony Doerr’s “All the Light We Cannot See” is a historical fiction book, with a wide-ranging language and characters who are both courageous and heartbreaking. Doerr brings together the stories of a French girl named Marie-Laure, who has lost her eyesight and a German orphan named Werner. As Hitler upsurges, Marie-Laure and Werner lives and families are torn apart by the war. Anthony Doerr 's’ use of imagery, and metaphor, he stresses the damage of life that war creates. Since the characters were affected by the war and also affected by their experiences, all characters went through a change

All The Light We Cannot See: Radio A spark ignites life within the embodiment of a metal case. As Werner, one of the main characters in the novel “All The Light We Cannot See”, mends the copper conduits a spark pulses through wire, circuitry and antenna. The sparks bend into vitality, crafted outside it’s engineered purpose. The vitality manipulates electromagnetic waves producing sound and thought.
War of the Worlds is an out of the box radio play that changed the world of mass communication forever and allowed the entire nation to see power of imagination and the unique power of radio over its audience. The creators of this nationwide hysteria were Orson Welles and the Mercury group. Orson Welles was a famous American actor, producer, director and radio broadcaster. In an effort to increase the shows audience, Orson Wells catered the idea of a Halloween public scare. The War of the Worlds radio play was a dramatization of H.G. Well’s novel The War of the worlds (1898 novel relating the story of an alien invasion on Earth) and performed as a scary Halloween episode on of the radio show Mercury Theater On The Air. The episode was aired over the Columbia Broadcasting System (CBS) on October 30th, 1938. The first two thirds of the 62-minute broadcast were presented as a series of simulated news bulletins, which suggested to many listeners that an actual alien invasion by Martians was currently in progress. Orson Welles’s scripted act was so convincing that the broadcast caused hysteria throughout the nation as several listeners believed that the nation was actually being invaded by Martians in a seemingly unstoppable attack. Many people were terrified by the news, and they left their homes in panic and fled. The aftermath of the broadcast was so disastrous that even Welles and his team were shocked. This 1938, 62 minute broadcast truly changed the meaning of mass media and everybody came to realize the true potential and power of mass communication.

In the story “The Adventure of the Speckled Band” the author Conan Doyle portrays many different narrative techniques. He uses these techniques to provide meaning for the audience as well as help them visualize the situation that was being described. The different techniques used are narrative discourse, suspense, conflict, close, and focalization in his story. Narrative discourses are events, to describe a series of events that are contingent one on another. Typically focuses on one or more performers of actions. Personal experience can influence narrative discourse due to the explaining of significant events in the life of the narrator. Narrative discourse is made up of setting, developing

Color photographs begin as black and white negatives. Color film consists of three layers of emulsion, each layer basically the same as in black and white film, but sensitive only to one third of the spectrum (reds, greens or blues). Thus, when colored light exposes this film, the result is a multilayered black and white negative
Tadao Ando is an architect of light, a master of space, and a builder for mankind. His work, realized primarily in precisely finished reinforced concrete, unifies building and nature to create a deep sense of sanctuary. Ando was born in Osaka, Japan in 1941. From the age of 10 to 17, he was employed as a carpenter, learning to work in wood in the Japanese tradition. His interest in architecture began when he obtained a book of Le Corbusier sketches when he was about 18. Ando is a self-taught architect. He apprenticed for brief periods with local designers and city planners, but primarily developed his skills by reading extensively, studying Japanese shrines, temples and tea houses, and making study
