A) \[66.2\]
B) \[1324\]
C) \[66.2\]
D) \[6.62\]
Correct Answer: A
Solution :
\[E=3\times {{10}^{-12}}erg\] \[\lambda =?\] \[h=6.62\times {{10}^{-27}}erg\text{-}s\] \[c=3\times {{10}^{10}}cm{{s}^{-1}}\] \[E=\frac{hc}{\lambda }\] \[3\times {{10}^{-2}}=\frac{6.62\times {{10}^{-27}}\times 3\times {{10}^{10}}}{\lambda }\] \[\lambda =\frac{6.62\times {{10}^{-27}}\times 3\times {{10}^{10}}}{3\times {{10}^{-12}}}\]You need to login to perform this action.
