Define energy gap.

The energy liberated in the ecombination of hole-electron pair is converted into electromagnetic radiation. If the aximum wave length emitted is 600 nm, find the value of forbidden energy gap.

The energy liberated in the ecombination of hole-electron pair is converted into electromagnetic radiation. If the maximum wavelength emitted is 500 nm, find value of forbidden energy gap.

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.
