Find the wavelength of light that may excite an electron in the valence band of diamond to the conduction band. The energy gap is 5.50 eV

For silicon , given Wavelength of light that excite an electron from the valence to the condiction band in silicon is

Compare valence band and conduction band.

Assertion : The electrons in the conduction band have higher energy than those in the valence band of a semiconductor Reason : The conduction band lies above the energy gap and valence band lies below the energy gap.
