- photoelectric emission of electrind from a metal surface does not take place below the threshold frequency which depends on the metal
- the number of electrons emmitted per second is proportinal to the intensity of the light if the frequency is above the threshold frequency
- photo electric emission occurs without delay (this is an assumption)
- when light is incident in a metal surface a electron at the surface gains a singl ephoton and gains energy equal to hf
- an electron can leave the surface if it gains more energy than the work function 0(the minimum energy needed by an electron to be liberated from the metal surface)
energy of a photon=hf
E=hf=hc/λ
EKMAX =hf-0
hf=EKMAX +0
FMIN =0/h
