A) \[2\times {{10}^{-15}}J\]
B) \[2\times {{10}^{-16}}J\]
C) \[2\times {{10}^{-17}}J\]
D) \[2\times {{10}^{-18}}J\]
Correct Answer: A
Solution :
Energy \[E=\frac{hc}{\lambda }=\frac{6.6\times {{10}^{-34}}\times 3\times {{10}^{8}}}{{{10}^{-10}}}\] \[=2\times {{10}^{-15}}J\]You need to login to perform this action.
