Question

Define Photoelectric effect ..​

Answer 1

Hey Mate...!!!

The photoelectric effect refers to the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light. ... Rather, he found the energies of the emitted electrons to be independent of the intensity of the incident radiation.

Answer 2

$\boxed{ \huge{ \bf{ \red{Answer :}}}}$

When a radiation of suitable frequency or wavelength is allowed to incident on a metal surface with low ionization energy, electrons are ejected from the metal. This phenomena is called Photoelectric effect and the electrons emitted are called photo electrons.
