Light of frequency v=1.5v(0) (where v(0)...

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_____.

Text Solution

Verified by Experts

Zero. [No photoelectric emission is possible if `v lt v_(0)`].

Light of frequency 1.5 times the threshold frequency is incident on a photo-sensitive material. If the frequency is halved and the intensity is doubled, the photoelectric current becomes

Assertion: Light of frequency 1.5 times the threshold frequency is incident on photo-senstive material. If the frequency is halved and intensity is doubled, the photo current remains unchanged. Reason: The photo electric current varies directely with the intensity of light and frequncy of light.
