The energy radiated by a black body at `2300K` is found to have the maximum at `a` wavelength `1260nm`, its emissive power being `8000Wm^(-2)`. When the body is cooled to a temperature `TK`, the emissive power is found to decrease to `500 Wm^(-2)`. Find :   `(i)` the temperature `T`   `(ii)` the wave length at which intensity of emission in maximum at the temperature `T`.
