1. No. of photons may not remain conserved as new photon may be created or the photon may be completely absorbed.

2. If the intensity of light of a given wavelength is increased, then no. of photons crossing a given area in a given time will increase. An increase in the intensity of incident radiation also increases the no. of electrons emitted from cathode per unit time, also increasing photocurrent.

3. Einstein got nobel for photoelectric effect in 1921, not for special theory of relativity. He put forward this theory in 1905 which is considered Einstein’s magical year when he published ground-breaking papers on photo electric effect and brownian motion and the Special Theory of relativity.

4. Stopping potential means the potential at which the electrons stop moving towards the anode due to negative voltage. Stopping potential V0 depends upon wavelength and work function f the metal, but not on intensity. 5. The photocurrent increases if the intensity of incident light is increased because the increase in the intensity of light consequently increases the number of electrons emitted per second ultimately increasing photocurrent.
