Photoelectric effect supports quantum na...

Photoelectric effect supports quantum nature of light because
(a) there is a minimum frequency of light below which no photo electrons are emitted
(b) the maximum kinetic energy of photo electrons depends only on the frequency of light and not on its intensity
(c ) even when the metal surface is faintly illuminated, the photo electrons leave the surface immediately
(d) electric charge of the photo electrons is quantised

A

There is'a minimum frequency below which no photoelectrons are emitted

B

The maximum kinetic energy of photoelectrons depends only on the frequency of light and not on its intensity

C

Even when the meal surface is fainlty illuminated the photoelectrons `(if vgt- v(th)` leave the surface immediately

D

electric charge of the photoelectrons is quantized
