When potassium metal is exposed to violet light

Assertion : The number of electrons ejected from a metal surface depend upon the frequency of light. Reason : There is a time lag between the striking of light beam and the ejection of electrons from the metal surface.

In photoelectric effect, the electrons are ejected from metals if the incident light has a certain minimum.
