Question

the kinetic energy of ejected electron emited​

Answer 1

Answer:

The kinetic energy of an ejected electron equals the photon energy minus the binding energy of the electron in the specific material. An individual photon can give all of its energy to an electron. The photon's energy is partly used to break the electron away from the material.
