The wavelength of light emitted by GaAs laser is 8670 x 10-10 m. If h = 6.626 x 10-34 Js, velocity of light = 3 x 108 m/s and eV = 1.602 x 10-19 J, the energy gap in GaAs is-A-0.18 eVB-0.7 eVC-1.43 eVD-2.39 eV-C-1.43 eV

Question

APTITUDE CRACK · Accepted Answer

C 1.43 eV Energy gap=hc/wavelength. Where h is Planck&#39;s constant. C is speed of light And this ans is in joule then it will be changed in eV.
