When a photon of light collides with a metal surface, number of electrons, (If any) coming out is

When a photon strikes a metal surface, a photoelectron in emission takes a time nearly

When a light of suitable frequency strikes a metal surface, then the number of ejected electrons :

A xenon are lamp is covered with an interference filter that only transmits light of 400 nm wavelength. When the transmitted light strikes a metal surface, a stream of electrons emerges from the metal. If the intensity of the light striking the surface is doubled, then

When green light is incident on a certain metal surface, electrons are emitted but no electrons are emitted with yellow light. If red light is incident on the same metal surface.

Assertion : When certain wavelength of light fall on metal surface it ejects electron. Reason : Light was wave nature.

Assertion : When certain wavelength of light fall on metal surface it ejects electron. Reason : Light was wave nature.

When an X -ray photon collides with an electrons and bounces off, its new frequency
