What is the frequency of a short wavelength?

Answer 1

The conventional definitions of wavelengths are as follows: * Shortwave band: 3,000 kHz to 30,000 kHz or 3–30 MHz * Medium wave band: generally 530-1700 KHz, used by AM radio stations worldwide * Longwave: 148.5 to 283.5 kHz, used mostly in Europe, Africa, the Middle East, etcetera, for AM radio broadcasting. It can be generalized that longwave is anything below 530 KHz, medium wave is 530 to 1700 KHz, and shortwave is anything from 1700 KHz to 30,000 KHz. A basic calculation for wavelength in meters is 300/F, where F is the frequency in megahertz. Thus a frequency of 30 MHz has a wavelength of 300 / 30 = 10 meters. A more common designation of radio bands is by frequency bands. Here's a PDF chart that shows those designations. http://www.arrl.org/hrlm/additions/2-17.pdf

Answer 2

Yes.

The product of [ (wavelength) times (frequency) ] gives the speed of the wave, which is always the same.

Since the product of the two quantities always produces the same number, you can see that if one increases,
the other one has to decrease.

Answer 3

When you see all the colors spread out, like in a rainbow for example,

you always see red at one end and violet at the other end.

The colors are always spread out in the order of their wavelengths.

Red is the longest visible wavelength, and violet is the shortest.

There are other wavelengths of 'light' that are longer than red or

shorter than violet, but they're not 'visible' just because the stuff in the

back of your eye doesn't respond to them even when they shine on it.

The shortest visible wavelength is around 400 nano (billionth of a) meters.

Answer 4

The shorter the wavelength, the higher will the frequency be - assuming the speed of the wave doesn't change. Specifically, the product of wavelength and frequency is equal to the speed of the wave.

Answer 5

Gamma Rays and you could also count in X-Rays if you wanted to be picky about it.
