# 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 Increses2. Increases when freq. Of photon increses3. Does not depend on freq but only on the intensity 4.intensity of the incident beam 4. Depend on both intensity and freq. Give me correct answer and method

As far as photoelectric effect is concerned it doesn't depend on intensity of light.
It only depends on frequency.
