Question

Related to photoelectric effect, in column I, some physical quantities change while in column II effects of these changes are given. Match the entries of column I with the entries of column II

Answer 1

Intensity of incident light changes implies saturation current changes.

Frequency of incident light changes implies, max KE changes and stopping potential changes.

Target material changes implies, work function changes. Hence, max KE and stopping potential change.

Potential difference between the emitter and collector changes implies time delay in emission of photoelectrons changes( it is almost instantaneous though).
