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.
