JEE MAIN - Physics (2023 - 25th January Evening Shift - No. 18)
Given below are two statements :
Statement I : Stopping potential in photoelectric effect does not depend on the power of the light source.
Statement II : For a given metal, the maximum kinetic energy of the photoelectron depends on the wavelength of the incident light.
In the light of above statements, choose the most appropriate answer from the options given below
Both Statement I and Statement II are incorrect
Statement I is correct but Statement II is incorrect
Both Statement I and Statement II are correct
Statement I is incorrect but Statement II is correct
Explanation
Statement I is correct as stopping potential is
independent of power of light used.
Statement II is correct as maximum kinetic energy of photoelectron depends on wavelength of light.
Statement II is correct as maximum kinetic energy of photoelectron depends on wavelength of light.
