According to the generality, electromagnetic waves are classified by taking their frequencies.
There are two such main methods, they can be classified with respect to the magnitude of the frequency, or for which purpose they are used.
Classification with respect to the magnitude of frequency
0 - 30 kHz : Very Low Frequency
30 - 300 kHz : Low Frequency
300 - 3000 kHz : Medium Frequency
3 - 30 MHz : High Frequency
30 - 300 MHz : Very High Frequency
300 - 3000 MHz : Ultra High Frequency
3 - 30 GHz : Super High Frequency
30 - 300 GHz : Extra High Frequency
Classification with respect to the usage/purpose
30 - 535 kHz - Naval and marine purposes
535 -1605 kHz - Medium wave region
1.6 - 30 MHz - Novice radio channels/international short transmissions
30 - 41 MHz - Governmental/non-governmental permanent/temporary tourist signals
41 - 68 MHz - Television channels 1-4
68 - 88 MHz - Governmental/non-governmental services
88 - 108 MHz - Frequency modulation (FM) radio waves
108 - 122 MHz - Aviation purposes
122 - 174 MHz - Governmental/non-governmental miscellaneous services
174 - 220 MHz - Television channels 5-12
220 - 470 MHz - Novice radio channels/Tourist signal transmissions
470 - 890 MHz - Television UHF channels
0.89 - 3 GHz - Aviation and naval purposes/radar signals transmission
3 - 30 GHz - Micro wave region
N.B.
The usage of some frequency regions might be differed from one region to another. The given is one of the most used classifications.

∙ 14y agoit contorls the channle, but t can also, mean different things!!!!!

∙ 12y agoThey are classified according to their wavelength.

∙ 13y agoThey are the same thing. Mark any point on a wave. When it goes 360 degrees ( to the same point on the next wave) that will be an entire wave therefore its' wave length.

What is the measurement between waves?
Distance between two waves is known as wavelength. Out of all electromagnetic spectrum, radio waves have the longest wavelength and gamma rays have the shortest wavelength. Waves that have less wavelength are highly energetic.
What is the distance of a wave measured by?
The answer depends on what kind of wave it is: a mechanical wave, or an electromagnetic wave with a long or short wavelength.
The distance between the crest of the one wave of electromagnetic radiation and the crest of the next one is its?
The distance between one crest of a wave and the next is called its wavelength.
The distance between one wave crest and another is known as the?
This distance is one wavelength
What is the distance between the crests of two waves?
That distance is called the wavelength.
What is the distance between two peaks or two troughs in an electromagnetic wave?
Wavelength
What is a wavelength?
The distance between consecutive crests of a wave. This serves as a unit of measure of electromagnetic radiation.

The distance between the crest of the one wave of electromagnetic radiation and the crest of the next one is its?
The distance between one crest of a wave and the next is called its wavelength.
What is the wavelength of an electromagnetic wave that has a 1 hz frequency?
The distance light takes to travel in a second (just less than 30000000metres).
What is the wavelength of an object?
The wavelength of a signal is calculated by c/f. C is the velocity of the wave and f the frequency of the signal. Wavelength is defined as the distance between any two successive crests or troughs in case of a mechanical wave. In case of longitudinal wave, the distance between two successive compressions or rarefactions will be the wavelength. In case of electromagnetic wave c/f will be the wavelength
The distance between one wave crest and another is known as the?
This distance is one wavelength
What is the distance between the crests of two waves?
That distance is called the wavelength.
The distance between two successive peaks on a wave is its?
The distance between successive identical parts of a wave is called the wave length.
How is wavelength related to energy?
The relationship between wavelength and energy depends on the type of wave. For electromagnetic waves, the shorter wavelengths are associated with higher energy levels. Electromagnetic energy travels in waves, and the length of the wave is inversely proportional to the energy the wave carries. Higher energy, shorter wavelengths. Lower energy, longer wavelengths.
Is wavelength measured in hertz or meters?
Usually, no. The wavelength of visible light is usually measured in nanometers. Only larger forms of electromagnetic radiation, like radio waves, are measured in meters.
