Light of frequency v=1.5v_(0) (where v_(0)=threshold frequency) is incident on a photosensitive material and photoelectric current is I. if the frequency of incident light is halved and the intensity of light is doubled then the photoelectric current becomes_____. |
| Answer» SOLUTION :ZERO. [No photoelectric emission is possible if `v lt v_(0)`]. | |
