Photoelectric Effect: Einstein's Equation

For a photosensitive material, work function is ' $W_0$ ' and stopping potential is ' V '. The wavelength of incident radiation is ( $h =$ Planck's constant, $c =$ velocity of light, $e =$ electronic charge)

Show answer and solution

Answer: (d)

Einstein's equation: $\frac{hc}{\lambda} = W_0 + eV$
$\lambda = \frac{hc}{W_0 + eV}$
So the answer is (d) $\frac{hc}{W_0 + eV}$ .
