(3 points) which statement correctly compares radio waves and microwaves? a. radio waves have a higher frequency than microwaves. b. radio waves have shorter wavelengths than microwaves. c. radio waves have lower radiant energy than microwaves. d. only radio waves are used in communication.

The correct answer is option C.

Explanation:

Radio waves and microwaves  both are the examples of electromagnetic waves.

Radio waves: These are waves with lowest frequency in the electromagnetic spectrum with longest wavelength.

Microwaves : These are the second lowest frequency waves in the electromagnetic spectrum with wavelength shorter than radio waves.

E = Energy of an electromagnetic wave

= Frequency of the electromagnetic wave

= Wavelength of the electromagnetic wave

Radio waves with longest wavelength has lower radiant energy than the microwaves.Hence, correct option is C.
