Question

Which figure shows the correct variation of applied potential difference (V) with photoelectric current (I) at two different intensities of light (I₁ < I₂) of same wavelengths :

(1)

(2)

(3) 

(4)

Answer 1

Correct option is : (3)

Given lights are of same wavelength. 

Hence stopping potential will remain same. 

Since I₂ > I₁, hence saturation current corresponding to I₂ will be greater than that corresponding to I₁.
