Question

Plot a graph showing the variation of photoelectric current as a function of anode potential for two light beams of same intensity but of different frequencies v1 and v2( v2>v1)

Answer 1

see graph, here it is clearly shown the variation of photoelectric current as a function of anode potential for two light beams of same intensity but of different frequencies v1 and v2.

We take radiations of different frequencies but of same intensity. for higher frequency, photoelectric current becomes higher and for lower frequency, photoelectric current becomes lower. but after a specific anode potential, photoelectric current for all radiation's different frequencies remains constant. this is known as saturation current.

hence, saturation current is independent from frequency of radiation.

Answer 2

Explanation:

here v2>v1 and intensities are same
