Two metal surfaces $A$ and $B$ have different work functions, such that the work function of $A$ is greater than the work function of $B$.

If the same light shines on both surfaces, emitting electrons from both, which of the following best describes the difference between the electrons emitted from the two surfaces?

A

Electrons emitted from $A$ have higher energy than those emitted from $B$.

B

Electrons emitted from $A$ have less energy than those emitted from $B$.

C

More electrons are emitted from $A$ than from $B$.

D

Fewer electrons are emitted from $A$ than from $B$.
