A light of wavelength '$$\lambda$$' and intensity '$$\mathrm{I}$$' falls on photosensitive material. If '$$\mathrm{N}$$' photo electrons are emitted, each with kinetic energy 'E', then

$$\mathrm{E} \propto \mathrm{I}, \mathrm{N} \propto \lambda$$

$$\mathrm{E} \propto \mathrm{I}, \mathrm{N} \propto \mathrm{I}$$

$$\mathrm{E} \propto \mathrm{I}, \mathrm{N} \propto \frac{1}{\lambda}$$

$$\mathrm{E} \propto \frac{1}{\lambda}, \mathrm{N} \propto \mathrm{I}$$
