Question

3. Two sound waves travel at a speed of 330
m/s. If their frequencies are also identical
and are equal to 540 Hz, what will be
the phase difference between the waves
at points 3.5 m from one source and 3 m
from the other if the sources are in phase?​

Answer 1

Answer:

Phase difference =ϕ=2π

λ

Δx

where Δx= path difference

And λ=

f

v

Hence,ϕ=2π

v

Δx.f

⟹ϕ=

330

0.4×540

×360

o

⟹ϕ=235.6
