Answer:
A static observer hears a sound whose frequency is appreciably different from actual frequency because here the change in frequency of the sound due to doppler effect.
Explanation:
Given that,
Frequency = f
We know that,
The sound source of frequency f moves with constant velocity through a medium that is at rest.
A static observer hears a sound whose frequency is significantly different from actual frequency due to doppler effect.
We know that,
The doppler effect is defined as
[tex]f=f_{0}(\dfrac{v+v_{0}}{v-v_{s}})[/tex]
Where, f₀ = actual frequency
f = observe frequency
v = speed of sound
[tex]v_{o}[/tex] = speed of observer
[tex]v_{s}[/tex] = speed of source
Hence, A static observer hears a sound whose frequency is significantly different from actual frequency because here the change in frequency of the sound due to doppler effect.
