A metal surface with a work function of W$0=$ hc$/500$ nm$$ is struck with blue light photons,$$and electrons are released.$$ If the blue light is replaced by red light of the same intensity, what is the result?$$

$[$Hint: Consider the energies of the blue and red light photons to compare with the work function!$]$

A$.$

emitted electrons are more energetic

B$.$

emitted electrons are less energetic

C$.$

more electrons are emitted in a given time interval

D$.$

fewer electrons are emitted in a given time interval

E$.$

no electrons are emitted
