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.

Answer :

Your answer is B. radio waves have shorter wavelenghts than microwaves.
Have a great day

Answer: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.

[tex]E=h\nu [/tex]

E = Energy of an electromagnetic wave

[tex]\nu=\frac{c}{\lambda }[/tex]

[tex]\nu \propto \frac{1}{\lambda }[/tex]

[tex]E\propto \frac{1}{\lambda }[/tex]

[tex]\nu [/tex] = Frequency of the electromagnetic wave

[tex]\lambda [/tex] = Wavelength of the electromagnetic wave

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