A source of sonic oscillations with freq...

A source of sonic oscillations with frequency `n_(0)=600Hz` moves away and at right angles to a wall with velocity `u=30ms^(-1)`. A stationary receiver is located on the line of motion of the source in the succession wall`to`source`to`receiver. If velocity of sound propagation is `v=330ms^(-1)`, calculate

Text Solution

Verified by Experts

The correct Answer is:
`R_(1), f_(beat) = 2f_(0)vu//(v^(2) - u^(2)) approx (2f_(0)u)/(v) = 1.0 Hz`
