Question
Light of frequency 1.5 times the threshold frequency is incident on photosensitive material. If the frequency is halved and intensity is doubled, the photo current becomes
Open in App
Solution
The correct option is D zero
When the frequency of incident light is halved
of its original value i.e. 1.5v0 then it becomes less than the threshold value. In
that case no photoelectric effect takes place. No photoelectrons would be emitted.
The photoelectric current becomes zero.
