A) \[13.27\,\times {{10}^{4}}\]
B) \[13.27\,\times {{10}^{34}}\]
C) \[1327\,\times {{10}^{34}}\]
D) \[1.71\times {{10}^{31}}\]
Correct Answer: D
Solution :
Number of photons emitted per second \[=\frac{Power}{hv}=\frac{10\times {{10}^{3}}}{6.6\times {{10}^{-34}}\times 880\times {{10}^{3}}}\] \[=1.71\times {{10}^{31}}\]
