Question

(3 Points)

Answer 1

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.

$E=h\nu$

E = Energy of an electromagnetic wave

$\nu=\frac{c}{\lambda }$

$\nu \propto \frac{1}{\lambda }$

$E\propto \frac{1}{\lambda }$

$\nu$ = Frequency of the electromagnetic wave

$\lambda$ = Wavelength of the electromagnetic wave

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

Answer 2

Your answer is B. radio waves have shorter wavelenghts than microwaves.
