Questions
Light of frequency 1.5 times the threshold frequency is incident on photo-sensitive material. If the frequency is halved and intensity is doubled, the photo current becomes
detailed solution
Correct option is D
(4)Suppose Threshold frequency is ν0. When the frequency of incident light is halved; it becomes ν02, which is less than threshold frequency. So no photo electron will be ejected.Talk to our academic expert!
