Suppose the energy liberated in the in the recombination of a hole-electron pair is converted into electromagnetic radiation.If the maximum wavelength emmited is 820nm,What is the band gap?

Suppose the energy liberated in the recombination of a hole-electron pair is converted into electromagnatic radiation. If the maximum wavelength emitted is 660nm, what is the band width? (Use h=6.6xx10^(-34) J-s)

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.

Suppose that the energy liberated in the combination of a hole-electron pair is conveted into electromagnetic radiation.If the maximum waveelngth of the radiation emitted is 630 nm,what is the width of forbbidden 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.

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.
