Question

A mosquito's wings create a buzzing noise with a frequency of 1050 Hz. If you hear a mosquito buzzing with a frequency of 1034 Hz, at what velocity is the mosquito travelling with respect to you (in m/s)?

Answer 1

5.26 m/s

Step-by-step explanation:

Given that,

The frequency of mosquito's wings, f = 1050 Hz

The observed frequency = 1034 Hz

We need to find the velocity of the mosquito travelling with respect to you. We have a formula to find it such that,

`v=(v)/((f')/(f))-v`

Where

v is the speed of sound

So,

`v=(340)/((1034)/(1050))-340\\\\v=5.26\ m/s`

So, the required velocity is equal to 5.26 m/s/
