1.5 e+7 Hertz (Hz) or 15 million Hertz.

Radio waves are a type of electromagnetic (EM) radiation with wavelengths in the electromagnetic spectrum longer than infrared light. They have have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers.

high frequency

Explanation:

because the high frequency has a wavelength range of 10m-100m

The frequency of radio waves with a wavelength of 20m is

1.5 e+7 Hertz (Hz) or 15 million Hertz.

This was obtained from the formula speed (c) is equal to the product of frequency (f) and wavelength (λ)

c = fλ

Since we are looking for the frequency, we will divide both sides of the formula above by the lamda symbol for wavelength, which gives us:

f = c / λ

The value of wavelength is already given which is 20 meters. The speed of radio waves is the same with the speed of light when travelling in a vacuum – also with the other electromagnetic waves. Hence the speed (c) is 3 e+8 m/s

f = 3 e+8 m/s   /    20m

f = 1.5 e+7 Hz

F=3x10^8m/s ÷ 15m
f=2x10^8 Hz

Given :-

Wavelength = 20 m

The realation between frequency and wavelength is :-

where C is Speed of light.

is frequency.

is wavelength.

Put the given value.
