A whistle emitting a sound of frequency ...

A whistle emitting a sound of frequency `440 h_(z)` is tied to a string of `1.5 m` length and roated with an angular velocity of `20 rad//s` in the horizontal plane. Calculate the range of frequencies heard by an observer stationed at a larger distance from the whistle .(Speed of sound =`330 m//s)` .

Text Solution

Verified by Experts

`v_S=romega=1.5xx20=30(m)/(s)`
`n_(min)=(v)/(v+v_S)n=(330)/(330+30)xx440Hz=403Hz`
`n_(max)=(330)/(330-30)xx440=484Hz`
