In photo electic effect we assume the photon energy is proportional to its freq. And is completely absorbed by the electrons in the metal. V > Vo then 1. Decreases when freq. Of phton Increses 2. Increases when freq. Of photon increses 3. Foes not depend onvfreq but only on the intensity 4.intensity of the incident beam 4. Depend on both intensity and freq. Give me correct answer and

The photoelectric current will depend on the intensity as the greater the intensity, the more photons there are. This means there will be more electrons emitted which will increase the current (because current is the flow of charge).
So, option 3 is correct.
