Which concept explains why frequencies of light that fell below the frequency threshold of the metal did not eject electrons? photons of different kinds of light carry different amounts of energy. photons are absorbed by atoms as soon as light strikes the metal. photons of light that has a frequency below the frequency threshold will not eject electrons.

Photons of different kinds of light carry different amounts of energy.

Explanation:

As per Einstein's Theory of photoelectric effect we know that

here we know that

= work function of the metal

KE = kinetic energy of ejected electron

= frequency of incident photon.

Now we know that photons of different frequency will have different amount of energy due to which the electrons get ejected out of the surface.

So if the photons have small energy or lesser energy then in that case the electron cannot ejected out

So threshold frequency is the minimum frequency at which electrons ejected out.
