Question

What is the wavelength of radio waves ?

Answer 1

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. idk fthis will help lol

Answer 2

Answer : The correct option is, $\text{more than }1\times 10^{-1}\text{meters}$

Explanation :

Electromagnetic waves : It is defined as a wave where two vectors are vibrating mutually perpendicular to each other and in the direction of the wave. The two vectors are the electric field and the magnetic field.

The gamma-rays, x-rays, ultraviolet-rays, infrared-rays, microwaves and radio-waves are the electromagnetic waves.

The increasing order of electromagnetic waves in terms of wavelength will be,

$\text{gamma-rays}$

The wavelength range of radio waves are, $10^3\text{ to }10^{-2}meters$

The frequency range of radio waves are, $10^4\text{ to }10^8Hz$

Therefore, the wavelength of radio waves is, $\text{more than }1\times 10^{-1}\text{meters}$

The electromagnetic waves spectrum are shown below.
