Dual Nature of Radiation question

2022 · 29 Jun · Shift 1 · Q47

JEE MainPhysicsDual Nature of RadiationMCQ+4 / −1
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R : Assertion A : The photoelectric effect does not takes place, if the energy of the incident radiation is less than the work function of a metal. Reason R : Kinetic energy of the photoelectrons is zero, if the energy of the incident radiation is equal to the work function of a metal. In the light of the above statements, choose the most appropriate answer from the options given below.
  1. A
    Both A and R are correct and R is the correct explanation of A.
  2. B
    Both A and R are correct but R is not the correct explanation of A.
  3. C
    A is correct but R is not correct.
  4. D
    A is not correct but R is correct.
