Question

ii) Einstein Photoelectric be written as E equation can hf - hfo What does each of the symbols used in the equation above represent?​

Answer 1

E = h f - h f0

E is the energy of the emitted photon - h f is the energy in an incident photon of frequency f

h f0 is the energy required to remove an electron from the metal being considered

If h f is not equal to or greater than h f0 then no photons will be emitted.
