A) 1332 Hz
B) 1372 Hz
C) 1412 Hz
D) 1454 Hz
Correct Answer: C
Solution :
\[\Rightarrow \] As both observer and source are moving, we can use the formula of apparent frequency as \[f={{f}_{0}}\left( \frac{v+{{v}_{0}}}{v+{{v}_{s}}} \right)\] \[=1392\left[ \frac{343+10}{343+5} \right]\] \[=1392\left[ \frac{353}{348} \right]Hz\] \[=1412\]You need to login to perform this action.
