Answer:

E = hv

E = hf

Explanation:

there are basically two equations for energy in light.

E = hf

where E is the energy of the photons. the unit is joules

h = the planck's constant . the unit is joules second

f = frequency of light. the unit is Hertz

E = hv

E is the energy of a particlar quantum under study.

h = planck,s constant which is usually 6.62607555 × 10^-34 js^-1

v = the frequency of the light.
