Question

An airplane traveling at half the speed of sound (v = 172 m/s) emits a
sound of frequency 5.00 kHz. At what frequency does a stationary
listener hear the sound as the plane approaches,and after it passes?

Answer 1

use these equations http://hyperphysics.phy-astr.gsu.edu/hbase/sound/dopp.html

Answer 2

thank you :)

Answer 3

no problem!

Answer 4

I wanna help u

Answer 5

First i wanna tell u abt the frequency which getting listener during approach

Answer 6

Required equation is
f'=(v/(v-vs))f

Answer 7

f'=?

Answer 8

Given
v=2*172m/s
vs=172m/s
f=5000hz

Answer 9

Feel free to ask for more clarification!!
