A) 1.11 f
B) 1.22 f
C) f
D) 1.27 f
Correct Answer: B
Solution :
When source and listener both are moving towards each other then, the frequency heard \[{n}'=n\,\left( \frac{v+{{v}_{O}}}{v-{{v}_{S}}} \right)\] Þ \[{n}'=f\,\left( \frac{v+v/10}{v-v/10} \right)=1.22\,f.\]You need to login to perform this action.
