Answer:
The energy of the photon is directly proportional to the frequency of the light emitting the photon.
Explanation:
Energy of the photon is given by expression:

E = Energy associated with the photon
= frequency of the light
h = Planck's constant =
c = speed of the light in vacuum = constant
=Wavelength of the photon

The energy of the photon is directly proportional to the frequency of the light emitting the photon.
