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

[IMAGE]

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 ...

...nd are produced by
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.

[IMAGE]

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.

Essay on The Electromagnetic Spectrum

- PART 1 The Electromagnetic Spectrum is the range of frequencies of possible electromagnetic radiation. The Spectrum ranges from 0 Hertz up to 2.4x1023 Hertz. The exact wavelength limits of the Spectrum are unknown however it is widely believed that the short wavelength limit is equal to the Planck Length (1.616x10-35m) and the long wavelength limit is the length of the Universe. Electromagnetic radiation (EMR) is an occurrence that takes the form of self-propagating waves produced by the motion of electrically charged particles, which can move through matter or a vacuum....   [tags: Physics]

Essay about Electromagnetic Spectrum for the Middle School Student

- Electromagnetic Spectrum for the Middle School Student Waves are all around us and come in various forms. Sound waves can travel through air because air is made of molecules, which carry the sound. Another type of wave is electromagnetic waves, which are different than sound waves because they don’t need molecules to travel. This means that electromagnetic waves can travel through air and solid materials as well as empty space (Groleau 2011). The electromagnetic spectrum consists of all waves of energy found in our universe....   [tags: Physics ]

Electromagnetic Spectrum Essay

- 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....   [tags: essays research papers fc]

My Spectrum Of Spinach Absorbance Graph Essay

- In my spectrum of spinach absorbance graph, the greatest peaks were at 435 nm, 465 nm, and a smaller peak at 670 nm. These values correspond to the approximate values of visible light wavelengths as indigo (445 nm), blue (475 nm) and red (650 nm)[3], respectively. This indicates that the spinach extract is the most absorbent of these colours and frequencies. The lowest absorbances were between 500 nm - 630 nm , which covers green (510 nm), yellow (570 nm), and orange (590 nm) light [3]. Green is a color that is reflected, and not absorbed by the spinach and this is indicative of the green colour that it appears as....   [tags: Light, Color, Electromagnetic radiation]
