A) \[0.04\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[0.40\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[4.00\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[40.0\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: A
Solution :
Doppler's shift, \[\Delta \lambda =\frac{v}{c}\lambda \] \[\Delta \lambda =\frac{r\omega }{c}\lambda \] ( \[\because \] \[v=r\omega \]) \[\Delta \lambda =\frac{r\lambda }{c}\left( \frac{2\pi }{T} \right)\] \[\left( \because \,\omega =\frac{2\pi }{T} \right)\] \[\Delta \lambda =\frac{7\times {{10}^{8}}\times 6000\times 2\times 3.14}{3\times {{10}^{8}}\times 25\times 24\times 3600}\overset{\text{o}}{\mathop{\text{A}}}\,=0.04\overset{\text{o}}{\mathop{\text{A}}}\,\]You need to login to perform this action.
