A) decrease by 5825.25 \[f\]
B) increase by 5966.75 \[f<{{f}_{r}}\]
C) decrease by 70.75 \[f={{f}_{r}}\]
D) increase by 70.75 \[f>{{f}_{r}}\]
Correct Answer: D
Solution :
\[[ML{{T}^{-1}}]\], \[[ML{{T}^{-2}}]\] Dopplefs shift \[[M{{L}^{2}}{{T}^{-2}}]\] or \[\frac{3aT}{2}\] \[\frac{aT}{2}\] As star is going away, so wavelength increases by \[\frac{aT}{4}\].You need to login to perform this action.
