A) \[6.36\times {{10}^{3}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]
B) \[6.36\times {{10}^{5}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]
C) \[6.64\times {{10}^{-8}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]
D) \[6.36\times {{10}^{18}}\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]
Correct Answer: C
Solution :
\[\Delta E=\frac{hc}{\lambda }\] or \[\lambda =\frac{hc}{\Delta E}\] \[=\frac{6.64\times {{10}^{-34}}\times 3\times {{10}^{8}}}{3\times {{10}^{-8}}}=6.64\times {{10}^{-8}}{\AA}\]You need to login to perform this action.
