A

no electrons will be emitted only photons can emit electrons

B

electrons can be emitted but all with an energy, `E_(o)`

C

electrons can be emitted with any energy, with a maximum of `E_(o)-phi` (`phi` is the work function)

To solve the problem, we need to analyze the situation where a beam of electrons with energy \( E_0 \) is incident on a metal surface. We will consider the possible outcomes of this interaction and determine the correct statement regarding the emitted electrons. ### Step-by-Step Solution: 1. **Understanding the Incident Beam**: - We have a beam of electrons, each with an energy \( E_0 \), striking a metal surface in an evacuated chamber. 2. **Types of Collisions**: ...

In a photoelectric effect , the K.E. of electrons emitted from the metal surface depends upon

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: 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.

The stopping potential for photoelectrons from a metal surface is V_(1) when monochromatic light of frequency upsilon_(1) is incident on it. The stopping potential becomes V_(2) when monochromatic light of another frequency is incident on the same metal surface. If h be the Planck’s constant and e be the charge of an electron, then the frequency of light in the second case is:

Assertion : Though light of a single frequency (monochromatic) is incident on a metal , the energies of emitted photoelectrons are different. Reason : The energy of electrons emitted from inside the metal surface is lost in collision with the other atoms in the metal.

Light of wavelength lambda is incident on metal surface. Work function of metal is very small compare to kinetic energy of photon. If light of wave length lambda' is incident on metal surface then linear momentum of electron becomes 1.5 of initial, find out lambda' .

Work function of Sodium is 2.75eV. What will be KE of emitted electron when photon of energy 3.54eV is incident on the surface of sodium?

Statement (A): Every photon striking the metal and colliding with the electron uses part of its energy to remove the electron from the metal surface, the remaining part is used to impart K.E. to the electron. Statement (B): The minimum energy needed to remove the electron from the metal surface is called work function. Statement (C): There is no time lag between incidence of photon and emission of photoelectrons.
