Question

Which statement correctly compares radio waves and microwaves?

Only radio waves are used in communication.


Radio waves have lower radiant energy than microwaves.


Radio waves have a higher frequency than microwaves.


Radio waves have shorter wavelengths than microwaves.

Answer 1

Radio waves have lower radiant energy than microwaves.

Step-by-step explanation:

Answer 2

Answer: Radio waves have lower radiant energy than microwaves.

Step-by-step explanation:

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them.

The electromagnetic radiations consist of radio waves, microwaves, infrared ,Visible , ultraviolet, X rays and gamma rays arranged in order of increasing frequency and decreasing wavelengths.

The relationship between wavelength and frequency follows inverse relation whereas relationship between energy and frequency follows direct relation.

Thus radiowaves with lower frequency will have more wavelength and lesser energy as compared to radio waves.
