The Doppler effect affects any wave, including electromagnetic waves. Basically, the idea of the Doppler effect is that the frequency of a wave increases when an object approaches you, and it decreases when it moves away from you. You can imagine that the sound waves, or electromagnetic waves, become compressed when the emitting object moves toward you.
The Doppler effect shows that far-away galaxies are moving away from us. This leads to the conclusion that the Universe is expanding.
That wave is called as electromagnetic wave. It has got a spectrum of very high frequency gamma rays to very low frequency radio waves. They all have the same speed. That is the speed of light.
Well, its got you looking at a computer screen, but I preferto point to TV and smart phones as examples of "effecting".===========================Answer #2 (from another contributor):Personally, I very much appreciate the electromagnetic waves in the thermaland visible bands, which I have shipped to me from the sun at very low cost.In addition, I earn a living, or at least enough to survive, by showing othershow best to use waves in the microwave bands.
Higher frequency, shorter wavelength light is at the "top" or "upper end" of the optical spectrum. You know the rainbow colors, and they start with red and go up to blue and violet (or purple). Red light is lower frequency, longer wavelength light. Wavelength decreases as frequency increases (always - one cannot be changed without changing the other). As we move up the spectrum, we come to the "end" of the part that is visible. Violet or purple is at the top. Above that is ultraviolet (UV) light, and it's got really short wavelengths and is really high in frequency. It has more energy than visible light. That's the stuff we block with sun screen. Above UV is the really high energy stuff like x-rays and cosmic rays. All this stuff is electromagnetic radiation (emr), and radio waves are at the lower or bottom end of the spectrum. A link is provided to the Wikipedia article on the electromagnetic spectrum so you can see kinda how it's laid out. It may help to lock in the concepts. The drawings are worth their weight in gold.
The answer i got is Forms of energy related to changes in matter include thermal energy, chemical energy, electromagnetic energy, and electrical energy.
it depends on the wavelength========================The frequency of any electromagnetic signal ... in fact the frequency of any wave ... is(speed of the wave)/(wavelength) .For light, that's 300,000,000/(wavelength in meters) , and the answer is in Hertz.The lowest frequency of light that your eye can detect is around 7.5 x 1014 Hz.That's 750,000,000,000,000 Hz ... 750,000 Gigahertz ! (for 400 nm wavelength)

i got a crush on you!! i <3 tyler prifrel!
The color of the star is more dependent on its size and temperature; the colors of strs vary. However, if the star was moving rapidly away from us, the color would be shifted to the red end of the spectrum from its natural color. This is calle redshift. A link can be found below for more inforation.

i would answer but then i got high
the got dead
