A) \[\frac{12395}{\Delta E}\times {{10}^{-10}}m\]
B) \[\frac{12395}{\Delta E}\times {{10}^{10}}m\]
C) \[\frac{12395}{\Delta E}\times {{10}^{-10}}cm\]
D) \[\frac{12395}{\Delta E}\times {{10}^{10}}cm\]
Correct Answer: A
Solution :
[a] \[\lambda =\frac{hc}{\Delta E}\] \[=\frac{6.62\times {{10}^{-34}}Js\times 3\times {{10}^{8}}m{{s}^{-1}}}{E\times 1.602\times {{10}^{-19}}J}\] \[=\frac{12395}{E}\times {{10}^{-10}}m\]You need to login to perform this action.
