In the photoelectric e ffect, electrons are never emitted froma metal ifthe frequency of the incoming light is be low a certainthreshold value. This is becauseA. Photons of lower-frequency light don' t have enough energyto eject an electron.B. The electric fi eld of low-frequency light does not vibrate theelectrons rapidly enough to eject them.C. The number of photons in low-frequency light is too small toeject electrons.D. Low-frequency light does not penetrate far enough into themetal to eject electrons.
