• A. intensity of incident light
• B. potential difference applied between the two electrodes
• C. the nature of emitter material
• D. frequency of incident light.

Answer 1

The correct option is D frequency of incident light.

Photoelectronic current depends on
(i) the intensity of incident light
(ii) the potential difference applied between the two electrodes.
(iii) the nature of the emitter material.
