Question

____ have more energy than ____.

A. Radio waves; visible light
B. Ultraviolet rays; X-Rays
C. Gamma rays; infrared rays
D. Radio waves; microwaves

Answer 1

The shorter the wavelength, the more energy it has.

Gamma rays have the shortest wavelengths (of all those listed, actually) , so the answer is C.

Answer 2

Answer : (C) Gamma rays; infrared rays

Explanation :

Energy of the wave is given by :

`E=(hc)/(\lambda)`

Where,

h is Planck's constant

c is the speed of the light

`\lambda` is wavelength

i.e. The energy of the wave is inversely proportional to the wavelength.

We know that the gamma rays has least wavelength i.e. having more energy.

So, the correct option is (C) " The gamma rays have more energy than infrared rays ".
