Vedclass · Answer

(B) In the photoelectric effect $(PEE)$,the intensity of incident light is directly proportional to the number of photons incident per unit area per unit time. Increasing the intensity increases the number of photoelectrons emitted,thereby increasing the photoelectric current. However,the maximum kinetic energy $(K.E.)$ of the ejected electrons and the stopping potential depend only on the frequency of the incident light,not its intensity. The work function is a property of the material and remains constant. Therefore,the work function remains unchanged.

If the intensity of incident light is increased in $PEE$,then which of the following is true?
