Question

Which of the following statement is true for the radio waves and the gamma rays?

Options

• The energy of gamma rays is lesser than that of the radio waves.

• The frequency of the radio waves is higher than that of gamma rays.

• The radio waves and the gamma rays have the same energy.

• The energy of radio waves is lesser than that of the gamma rays.

Answer 1

The energy of radio waves is lesser than that of the gamma rays.

Explanation:

Gamma rays have a much higher frequency than radio waves.

This is due to the direct proportionality between energy and frequency.

E = hv 

Therefore, radio waves have lower energy than gamma rays.
