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.

What is the distance between two peaks or two troughs in an electromagnetic wave?

The distance between two peaks or two troughs in an electromagnetic wave is known as the wavelength. It is the distance over which the wave's shape repeats. The wavelength is inversely proportional to the frequency of the wave, with shorter wavelengths corresponding to higher frequencies.


What is the distance between two peaks in a electromagnetic wave is called?

The distance between two peaks in an electromagnetic wave is called the wavelength. It is typically measured in meters.


What is longer an electromagnetic wave's wavelength the?

The longer an electromagnetic wave's wavelength, the lower its frequency. This means there are fewer wave crests passing a point in a given time, resulting in a longer distance between crests.


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 an example of wavelength?

An example of wavelength is the distance between two consecutive peaks of a wave, such as the distance between two successive crests of an ocean wave or two peaks of a sound wave. In electromagnetic radiation, the wavelength is the distance between two successive peaks of the wave, like the distance between two peaks of a light wave.


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).


Does an electromagnetic wave have amplitude wavelength and frequency?

Yes, an electromagnetic wave has an amplitude, wavelength, and frequency. The amplitude represents the wave's maximum displacement from its midpoint, the wavelength is the distance between two consecutive peaks (or troughs) of the wave, and the frequency is the number of complete wave cycles that pass a certain point in one second.


What is the significance of one wavelength in the context of electromagnetic radiation?

One wavelength in electromagnetic radiation is significant because it represents the distance between two consecutive peaks or troughs of a wave. This measurement is important in determining the frequency and energy of the radiation, as well as its properties such as color or type.


What is a wavelegth?

A wavelength is the distance between two consecutive points of a wave that are in phase, such as two peaks or two troughs. It is commonly used to describe electromagnetic waves, sound waves, and other types of waves. The longer the wavelength, the lower the frequency of the wave.


What is the average distance between a wave peaks?

The average distance between wave peaks, also known as the wavelength, varies depending on the type of wave. For ocean waves, the average wavelength ranges from about 30 meters to 150 meters. In electromagnetic waves, such as light waves, the average wavelength can range from fractions of a millimeter to kilometers.


What is the distance of a wave measured by?

The distance of a wave is typically measured by its wavelength, which is the distance between two consecutive points that are in phase with each other. This can be measured in units such as meters or nanometers, depending on the scale of the wave.


What do electromagnetic waves vary in?

Electromagnetic waves vary in their frequency and wavelength, which are inversely related. Frequency is the number of wave cycles that pass a given point per second, while wavelength is the distance between successive wave peaks. Additionally, electromagnetic waves also vary in their energy, with higher frequency waves having higher energy levels.
