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

Options

A. The mass of 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 the red light
C. The mass of photon of violet light is equal to the mass of the red light
D. The mass of photon of violet light may be greater or smaller than the mass of the red light depeding upon the surrounding conditions

Answer

a

Explanation

According to Einstein's, mass of a photon is given
by the relation,
`E=hv=mc^2 or m=(hc)/(c^2) or m prop v`
Since frequency of violet light photongt frequency
of red light photon,
`:.` mass of violet photon is greater than the
mass of red photon.
