A) \[1.215\times {{10}^{-7}}m\]
B) \[1.215\times {{10}^{-5}}m\]
C) \[1.215\times {{10}^{-4}}m\]
D) \[1.215\times {{10}^{-3}}m\]
Correct Answer: A
Solution :
Energy radiated \[E=10.2\,eV=10.2\times 1.6\times {{10}^{-19}}J\] Þ \[E=\frac{hc}{\lambda }\] Þ \[\lambda =1.215\times {{10}^{-7}}m\]You need to login to perform this action.
