Electromagnetic radiation with maximum wavelengths is :

Electromagnetic radiation with maximum wavelength is-

The energy liberated in the ecombination of hole-electron pair is converted into electromagnetic radiation. If the maximum wave length emitted is 400 nm, find the value of forbidden energy gap.

What do you mean by photo electric effect? Calculate the energy of one mole of photons of radiations having wave length 200 nm.
