PhysicsThe wave length of the sound produced by a source is 0.8m. If the source moves towards the stationary listener at 32 ms–1, what is the apparent wave length of sound if the velocity of sound is 320 ms–1

The wave length of the sound produced by a source is 0.8m. If the source moves towards the stationary listener at 32 ms^–1, what is the apparent wave length of sound if the velocity of sound is 320 ms^–1

A
0.32 m
B
0.4 m
C
0.72 m
D
0.80 m

Solution:

$λ_{1} = (\frac{V - V_{s}}{V}) λ = [\frac{320 - 32}{320}] 0.8 = \frac{288}{320} x 8 x 10^{- 1} = 0.72 m$
