A source and listener are both moving towards each other with a speed v/10 where v is the speed of sound. If the frequency of the note emitted by the source is f, what will be the frequency heard by the listener?

Text Solution

Verified by Experts

When source and listener are both moving towards each other, the apparent frequency is
`n.=((v+v_(t))/(v-v_(s)))n`
`n.=((v+(v)/(10))/(v-(v)/(10)))n`
`n.=(11)/(9).f`
`=1.22f`
