E = hf − w w = ?

Group of answer choices

E/hf

−E/hf

E + hf

hf − E

The strength of each photon is E = hf, where h is Planck's consistent and f is the frequency of the EM radiation. ... Individual photons interact with individual electrons. Thus if the photon energy is too small to smash an electron away, no electrons will be ejected.

Hope it helps =)
