Question

The curves a, b, c and d shows the variation between the applied potential difference $\left(V\right)$ and the photoelectric current $\left(i\right)$ at two different intensities of light $(I_1>I_2)$. Which of the following figure is correct?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Increasing intensity will only increase in number of photons hitting the surface which will increase the magnitude of current but there will be no change in kinetic energy of the electron or stopping potential.
