The fig. shows the variation of photon current with anode potential for a photo-sensitive surface for three different radiation. Let `I_(a), I_(b) and I_(c)` be the intensities and `f_(a), f_(b) and f_(c)` be the frequency for the curves a,b and c respectively.

A

`f_(a) = f_(b)`

B

`I_(a) lt I_(b)`

C

`f_(c) lt f_(b)`

D

`I_(c) gt I_(b)`

Text Solution

Verified by Experts

The correct Answer is:
C
Here `I_(B) = I_(C) gt I_(a)` and `f_(c) gt f_(a) = f_(b)`
