Statement-1: The photoelectrons produced by a monochromatic light beam incident on a metal surface have a spread in their kinetic energies.
Statement-2: The work function of the metal varies as a function of depth form the surface.

A:When monochromatic beam of light is incident on metal surface ,it is dispersed in form of kinetic energy. R:Work function of metal depend on depth of metal.

For a monochromatic light incident on a metal surface, the stopping potential is V. Then the kinetic energy of the fastest photoelectrons emitted from that surface is

Stopping potential for a monochromatic light of a metal surface is 4V. What is the maximum kinetic energy of photoelectron

Light of wavelength 4000 Å is incident on a metal surface. The maximum kinetic energy of emitted photoelectron is 2 eV. What is the work function of the metal surface ?

Light of wavelength 4000A∘ is incident on a metal surface. The maximum kinetic energy of emitted photoelectron is 2 eV. What is the work function of the metal surface?

Statement 1: Though light of a single frequency (monochromatic light) is incident on a metal, the kinetic energies of emitted photoelectrons are not equal. Statement 2: The energy of electrons just after they absorb photons incident on metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

Statement 1: Though light of a single frequency (monochromatic light) is incident on a metal, the kinetic energies of emitted photoelectrons are not equal. Statement 2: The energy of electrons just after they absorb photons incident on metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

When light incident on a metal has energy less than the work function of the metal, then no electron is emiited from the surface of the metal. Mathematically justify this statement.
