Vedclass · Answer

(A) The energy gap $E_g$ is given as $1.14 \ eV$. To find the maximum wavelength $\lambda_{\max}$ that can be absorbed,we use the relation $E_g = \frac{hc}{\lambda_{\max}}$. Rearranging for $\lambda_{\max}$,we get $\lambda_{\max} = \frac{hc}{E_g}$. Substituting the values: $h = 6.626 	imes 10^{-34} \ J \cdot s$,$c = 3 	imes 10^8 \ m/s$,and $E_g = 1.14 	imes 1.6 	imes 10^{-19} \ J$. $\lambda_{\max} = \frac{6.626 	imes 10^{-34} 	imes 3 	imes 10^8}{1.14 	imes 1.6 	imes 10^{-19}} \approx 1.0888 	imes 10^{-6} \ m$. Converting to $\mathring A$: $1.0888 	imes 10^{-6} \ m = 10888 \ \mathring A$.
