A) \[0.033\,\,{AA}\]
B) \[0.33\,\,{AA}\]
C) \[3.3\,\,{AA}\]
D) \[33\,\,{AA}\]
Correct Answer: A
Solution :
\[\Delta \lambda =\lambda .\frac{v}{c}\]where \[v=r\omega =r\times \left( \frac{2\pi }{T} \right)\] \[\therefore \Delta \lambda =\frac{4320\times 7\times {{10}^{8}}\times 2\times 3.14}{3\times {{10}^{8}}\times 22\times 86400}=0.033{AA}\]
