Question

what so you understand by energy gap?

Answer 1

The term "band gap" refers to the energy difference between the top of the valence band and the bottom of the conduction band. ... Electrons can gain enough energyto jump to the conduction band by absorbing either a phonon (heat) or a photon (light).

Answer 2

tthe gap between the energy into not passes through the light and deep is it has the ultraviolet rays it help in many ways to us like it helps to give electricity etc.
