A) \[6.62\times {{10}^{-10}}\text{J}\]
B) \[19.86\times {{10}^{-24}}\text{J}\]
C) \[6.62\times {{10}^{-28}}\text{J}\]
D) \[2.2\times {{10}^{-35}}\text{J}\]
Correct Answer: C
Solution :
Energy of photon, \[E=\frac{hc}{\lambda }\] \[=\frac{6.6\times {{10}^{-34}}\times 3\times {{10}^{8}}}{3\times {{10}^{2}}}\] \[=6.6\times {{10}^{-28}}J\]
