The Maximum Kinetic Energy Of Emitted Electrons In A Photoelectric Physics QuestionThe Maximum Kinetic Energy Of Emitted Electrons In A Photoelectric Physics Question

The maximum kinetic energy of emitted electrons in a photoelectric effect does not depend upon

Options

(a) Intensity
(b) Work function
(c) Wavelength
(d) Frequency

Correct Answer:

Intensity

Explanation:

The maximum kinetic energy = hʋ – W₀

where hʋ is the incident energy and W₀ is the energy of extraction.

If one increases the intensity for a radiation which produces photo electricity, there is no change in kinetic energy.
