A source and a listener are both moving towards each other with speed `v//10`, where `v` is the speed of sound. If the frequency of the note emitted by the source is `f`, the frequency heard by the listener would be nearly
A
1.11f
B
1.22f
C
f
D
1.27 f
Text Solution
Verified by Experts
The correct Answer is:
B
`f'=((V+V_(0))/(V-V_(s))) f` `f'=((V+V/10)/(V-V/10)) f =1.22 f`
