A) \[1.2\,f,\lambda \]
B) \[f,1.2\,\lambda \]
C) \[0.8f,0.8\lambda \]
D) \[1.2\,f,1.2\,\lambda \]
Correct Answer: A
Solution :
\[n'=\frac{v+{{v}_{0}}}{v}.n=\frac{v+v/5}{v}.f=\frac{6}{5}f=1.2f\]and since the source is stationary, so wave length remains unchanged for observer.You need to login to perform this action.
