Suppose a metal surface has a work function of $3.4\times {10}^{-19}\text{ J}$.

If a 500 nm light is incident on the metal surface, what is the maximum energy of an ejected electron?

Note:

  • $h=6.626\times{10}^{-34}\text{ J s}$
  • $c=3.00\times{10}^{8}\text{ m/s}$
A

$5.8\times{10}^{-20}\text{ J}$

B

$7.7\times{10}^{-20}\text{ J}$

C

$1.5\times{10}^{-19}\text{ J}$

D

$4.0\times{10}^{-20}\text{ J}$
