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.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) When a light of single frequency falls on the `e^-` of inner layer of metal, then this `e^-` comes out of the metal surface after a large number of collisions with atoms of its upper layer.

In each of the following questions, a statement is given and a corresponding statement or reason is given just below it. In the statement, mark the correct answer as Statement-I: Though light of a single frequency (monochromic light) is incident ona metal, the energies of emitted photoelectrons are different Statement-II: The energy of electrons just after they absorb photons incident on the metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

Some questions (Assertion-Reason Type) are given below. Each question contains Statement I (Assertion) and statement II(reason). Each question has 4 choices (a),(b),(c ) and (d) out of which only one is correct. So select the correct choise. a. Statement I is True, Statement II is True,Statement II is a correct explanation for Statement I b. Statement I is True, Statement II is True, Statement II is NOT a correct ecplanation for Statement I c. Statement I is True, Statement II is False . d. Statement I is false, Statement II is True. 2. Statement:I Though light of a single frequency (monochromatic light) is incident on a metal, the energies of emitted photoelectrons are different. Statement II: The energy of electrons just after they absorb photons incident on the metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

The photoelectrons emitted from a 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.
