A

there is a minimum frequency below which no photoelctrons are emitted

B

the maximum kinetic energy of photoelctrons depends only on the frequency of light and is independent of intensity.

C

even when the metal surface is illuminated with very small intensity the photoelectrons ( if `v gt v_(th)`) leave the surface immediately

D

electric charge of the phtoelectrons is quantized
