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.

What wave has a color spectrum that is known as roygbiv?

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.


What waves that have the longest wavelength and are used to carry audio and picture signals over long distances are known as?

They are called as radio waves. They have got the speed of light. The wave length of the radio wave may be up to few kilometers.


How do electromagnetic waves effect your every day lives?

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.


What kind of light has a very high frequency and a very short wavelength?

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.


Where did danisnotonfire get his sound effect?

Dan Howell, also known as danisnotonfire, got his sound effect from a YouTube channel called freesound.org. He used the sound effect in his videos as a signature feature that became popular among his fans.
