Light with a Wavelength Of $310 \mathrm {~nm}$ Is Incident on a Metal That Has a Work Function

Multiple Choice

Light with a wavelength of $310 \mathrm {~nm}$ is incident on a metal that has a work function of $3.80 \mathrm { eV }$ . What is the maximum kinetic energy that a photoelectron ejected in this process can have? $( 1 \mathrm { eV } = 1.60 \times$ $\left. 10 - 19 \mathrm {~J} , c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } \right)$

A) $0.36 \times 10 ^ { - 19 } \mathrm {~J}$
B) $0.62 \times 10 ^ { - 19 } \mathrm {~J}$
C) $0.21 \times 10 ^ { - 19 } \mathrm {~J}$
D) $0.48 \times 10 ^ { - 19 } \mathrm {~J}$
E) $0.33 \times 10 ^ { - 19 } \mathrm {~J}$
