1.

Consider a source moving towards an listener at a speed of 0.9v. Where v is the velocity of sound. Calculate the apparent frequency if the actual frequency is 600 Hz.

Answer»

SOLUTION :Apparent frequency, `N.=((v)/(v-v_(s)))n`
`v_(s)=0.9v,n=600Hz`
`n.=((v)/(v-0.9v))600=((v )/(v(1-0.9)))600=(1)/(0.1)XX600`
`n.=6000Hz`
