A) 1.00
B) 1.02
C) 1.04
D) 0.98
Correct Answer: A
Solution :
Number of photons emitted per second \[n=\frac{p}{\left( \frac{hc}{\lambda } \right)}\] \[\therefore \] \[p=\frac{nhc}{\lambda }\] \[\Rightarrow \frac{{{p}_{2}}}{{{p}_{1}}}=\frac{{{n}_{2}}{{\lambda }_{1}}}{{{n}_{1}}{{\lambda }_{2}}}=\frac{1.02\times {{10}^{15}}\times 5000}{{{10}^{15}}\times 5100}=1\]You need to login to perform this action.
