Recommended: Full description of electromagnetic spectrum

The electromagnetic spectrum is the range of all electromagnetic radiation. The electromagnetic radiation can be radio waves that we use to listen to music, visible light that we use to see or microwaves that we use to cook food with. We deal with all of these types of radiations in our daily lives.
RADIO WAVES: Radio waves are used exactly for what it says — radio. They are also the waves responsible for the signals cell phones and televisions receive. Objects in space, such as planets and comets, giant clouds of gas and dust, and stars and galaxies, emit radio waves.
MICROWAVE: Microwaves are used to heat up food in a microwave oven. It is also used by astronomers to study the structures of nearby galaxies.
INFRARED: Night vision goggles work by using infrared to show the viewer the emitted heat from objects and other people. It is also used in space to map the dust between different stars.
VISIBLE LIGHT: This is the only part of electromagnetic spectrum that human beings can see. Visible light is emitted by things like the Sun, light-bulbs or TVs.
ULTRAVIOLET: UV light is ho...

    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

  • An Analysis of William T. Vollmann’s The Visible Spectrum

    1897 Words  | 4 Pages

    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.

    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.

    Radio-wave technology is one of the most important technologies used by man. It has forever changed the United States and the world, and will continue to do so in the future. Radio has been a communications medium, a recreational device, and many other things to us. When British physicist James Clerk Maxwell published his theory of electromagnetic waves in 1873, he probably never could have envisioned the sorts of things that would come of such a principle. His theory mainly had to do with light waves, but fifteen years later, a German physicist named Heinrich Hertz was able to electrically generate MaxwellÕs ÒraysÓ in his lab. The discovery of these amazing properties, the later invention of a working wireless radio, and the resulting technology have been instrumental to AmericaÕs move into the Information Age. The invention of radio is commonly credited to Guglielmo Marconi, who, starting in 1895, developed the first ÒwirelessÓ radio transmitter and receiver. Working at home with no support from his father, but plenty from his mother, Marconi improved upon the experiments and equipment of Hertz and others working on radio transmission. He created a better radio wave detector or cohere and connected it to an early type of antenna. With the help of his brothers and some of the neighborhood boys he was able to send wireless telegraph messages over short distances. By 1899 he had established a wireless communications link between England and France that had the ability to operate under any weather conditions. He had sent trans-Atlantic messages by late 1901, and later won the Nobel prize for physics in 1909. Radio works in a very complicated way, but hereÕs a more simple explanation than youÕll get from most books: Electromagnetic waves of different wavelengths are produced by the transmitter, and modulations within each wavelength are adjusted to carry ÒencodedÓ information. The receiver, tuned to read the frequency the transmitter is sending on, then takes the encoded information (carried within the wave modulations), and translates it back into the sensory input originally transmitted. Many of the men who pioneered radio had designs for it. Marconi saw it as the best communication system and envisioned instant world-wide communication through the air. David Sarnoff ( later the head of RCA and NBC) had a vision of Òa radio receiver in every homeÓ in 1916, although the real potential of radio wasnÕt realized until after World War I.

    Cell phones represent a type of technology that has been around for more than over fifty years; it has only been recently that many people began to use cell phones as a major part of their everyday life. In the past cell phones were for business people to conduct their business, but in today’s society every one owns a cell phone. Cell phones are interesting, useful and also play a major role in our life’s bringing people closer and keeping in touch with one another. Most people do not know and understand the physics of a cell phone. Cell phones are also known as cellular phone, hand phone, and commonly known as a mobile phone. A cell phone is an electric device that can make and receive calls, over and automatic repeat request (radio link petrol -RLP) used over wireless air interdace.it us a portable telephone that uses and receive phone signals.it also divides that earth into small regional called cells.in the resent estimates there are over 190 million people using mobile phone.

    An example of a communications satellite is the EchoStar 3.  It is used to send TV signals to homes in North America.  For this simple use of broadcasting TV through these technical machines, there are over one hundred communications satellites orbiting earth today. Communication satellites are also used as relay stations in space.  People use them to bounce messages from one part of the world to another.  These messages can be telephone calls, TV pictures, or even Internet connections.  Many communications satellites have footprints.  Communication satellites like the EchoStar 3 are in a geosynchronous orbit.  This means that the satellite always stays over one spot on Earth.  The area on Earth that it can see is called the satellite's footprint.  For example a footprint that covers all of Africa can be used by one person to send a message to another person in Africa.  One could also use communications satellites as relay stations to send messages to people over a system of satellites with many footprints.
