Q. Assertion :If the frequency of the incident light on a metal surface is doubled, the kinetic energy of emitted electrons is more than doubled
Reason: The metal will provide additional energy to the emitted photoelectron for light of higher frequency than that for lower frequency

Dual Nature of Radiation and Matter

Solution:

Correct answer is (a) If both assertion and reason are true and reason is the correct explanation of assertion
