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

AI Generated Solution

To solve the problem, we need to calculate the maximum and minimum frequencies heard by an observer due to the Doppler effect, as the whistle is rotating in a circular path. Here’s the step-by-step solution: ### Step 1: Identify the given data - Frequency of the whistle, \( f_0 = 440 \, \text{Hz} \) - Length of the string (radius of circular motion), \( r = 1.5 \, \text{m} \) - Angular velocity, \( \omega = 20 \, \text{rad/s} \) - Speed of sound, \( c = 330 \, \text{m/s} \) ...
