C) 0.012 to\[\overset{o}{\mathop{\text{A}}}\,\]
D) 0.024 to\[\overset{o}{\mathop{\text{A}}}\,\]
Correct Answer: A
Solution :
\[\lambda =\frac{hc}{E}\] \[=\frac{6.6\times {{10}^{-34}}\times 3\times 1.8}{(0.51+0.51)\times {{10}^{6}}\times 1.6\times {{10}^{-19}}}\] \[=1.21\times {{10}^{-12}}m\] \[=0.012\overset{o}{\mathop{\text{A}}}\,\]
