Electromagnetic spectrum?I don't even know what that means..?

Question

I was asked to describe the detrimental effects of excessive exposure of certain components of the electromagnetic spectrum.

How do I do this?Are there any good websites for this?Do you know the answer...

Answer 1

Electromagnetic spectrum means radio waves / microwaves / infra-red light / visible light / ultraviolet light/ x-rays / gamma rays. In order of increasing energy. All forms can have detrimental effects on the body (I assume you mean humans). The lower energy waves can cause damage by heating (like microwaves), the higher energies by breaking down the molecular and atomic components of living tissue.

Answer 2

The electromagnetic (EM) spectrum is the range of all possible electromagnetic radiation. The "electromagnetic spectrum" (usually just spectrum) of an object is the characteristic distribution of electromagnetic radiation from that object.The electromagnetic spectrum, extends from below the frequencies used for modern radio (at the long-wavelength end) through gamma radiation (at the short-wavelength end), covering wavelengths from thousands of kilometres down to a fraction the size of an atom. It's thought that the short wavelength limit is the vicinity of the Planck length, and the long wavelength limit is the size of the universe itself (see physical cosmology), although in principle the spectrum is infinite and continuous. Here is the order of the spectrum: Radiowaves Microwaves Infrared Visible Light Ultra Violet X Rays Gamma Rays Hope this helped!! I'm pretty sure it is all right, I learned it in school last year!

Answer 3

In a nut shell without the baffle the electromagnetic spectrum is the entire range of frequencies that exist with radio waves.
From the long wave frequencies of infra red and visible light to the very short frequencies of gamma rays.

No matter if you can see it as light say from the sun or a light bulb or feel it as heat from a fire or an x-ray taken to tuning into your favorite tv or radio station they are all electromagnetic waves depending on the frequency gives it the effect we notice such as light, heat, x-rays, radio.

Answer 4

Well one detrimental effect is a sunburn from too much ultraviolet light. Another is burns period. Infrared light is heat essentially. Blindness is another. The electromagnetic spectrum is every type of electromagnetic wave ie. visible light, microwaves, radio waves, infrared light, ultraviolet light. Just look up electromagnetic spectrum on www.google.com. I'm sure they have a good article.

Answer 5

The entire range of radiation extending in frequency from approximately 1023 hertz to 0 hertz or, in corresponding wavelengths, from 10-13 centimeter to infinity and including, in order of decreasing frequency, cosmic-ray photons, gamma rays, x-rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radio waves.

Answer 6

This is the spectrum of waves that exist. This also includes radioactive alpha, beta, and gamma waves. Radiation=cancer. I think google should be able to help you with more infor on this...

Answer 7

try these sites...
i had an assignment about that a year ago...
my references are these sites:

hope these are helpful to you!
bye...
good luck...
