Question

What occurs in the photoelectric effect when light of suitable frequency falls on a metal surface?

पर्याय

• Electrons are emitted from the metal surface.

• The work function of the metal becomes zero.

• Every photon loses its frequency.

• Photons are deflected by the metal surface.

Answer 1

The photoelectric effect is the emission of electrons from a metal surface when light of suitable frequency falls on it. The photon model explains this emission through the energy carried by individual photons.
