A) \[6.67\times {{10}^{15}}\]
B) \[6.67\times {{10}^{11}}\]
C) \[4.42\times {{10}^{-15}}\]
D) \[4.42\times {{10}^{-18}}\]
Correct Answer: D
Solution :
\[\frac{hc}{\lambda }=\frac{6.63\times {{10}^{-34}}\times 3\times {{10}^{8}}}{45\times {{10}^{-9}}}=4.42\times {{10}^{-18}}J\]You need to login to perform this action.
