Einstein's Photoelectric Equation is :

K_max = hv - Φ

where v is the frequency of the incident radiation and K_max is the maximum possible kinetic energy of photoelectron. The work function Φ is given as :

Φ = hv₀ . In terms of stopping potential, K_max = eV_0.

What can you say about the following statement?

Statement: All photons are of same energy.

False

Photon energy depends upon the frequency.
