Multiple Choice: Please select the best answer and click "submit " How does quantum theory explain the working of a photocell? An electron is only released from an atom when struck by a photon of light with a certain minimum energy. Each light wave with an energy below a certain value releases an electron from an atom. Each photon of light with an energy below a certain value releases an electron from an atom. Each electron is released from an atom when a light wave with a certain minimum energy strikes it.

Explanation / Answer

Option A is correct.

Option C can be simply eliminated because the energy has to be minimum and there is no limit on the upper bound of energy value.

Option B & D talks about the wave nature of light while quantum theory distributes the energy of lights in form of packets called photons. Hence Option A is correct
