Answer:
E = hv
E = hf
Step-by-step 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.
