Dual Nature of Radiation and Matter: RE-NEET 2026

Easy· Experimental Study of Photoelectric Effect (Effect of Intensity of Light on Photocurrent)· +4 / −1

A beam of light falls on a metal surface such that photo-electrons are generated. If power of the light source starts to decrease linearly with time

t

, then variation of the photocurrent

I

and magnitude of the stopping potential

|V|

with time is best represented by: Each option shows two graphs:

I

versus

t

(left) and

|V|

versus

t

(right).
