Comparing the masses of the two photons, of red light and violet light

Moderate

A

The mass of the photon of violet light is greater than the mass of the red light
B

The mass of photon of violet light is less than the mass of red light
C

The mass of photon of violet light is equal to the mass of red light
D

The mass of photon of violet light may be greater or smaller than the mass of the red light depending upon the surrounding conditions

Solution

According to Einstein’s equation mass of a photon is given by the relation
$E = h ϑ = m c^{2}$
Or $m = \frac{h ϑ}{c^{2}} o r m \propto ϑ$
Since frequency of violet light photon is greater than the frequency of red light photon.
Mass of violet photon is greater than the mass of red photon
