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:

G1 Physics · Accepted Answer

For the same wavelength, the stopping potential remains the same. Since I₂ > I₁, the saturation current for intensity I₂ is greater than that for intensity I₁. Therefore, Image 3 is correct.
