Physics

Answer:

b. depends upon the medium in which it occurs

Explanation:

When source of sound and observer moves relative to each other then in that case the relative motion between them will change the frequency that is observed by the observer.

It is known as Doppler's effect. In that case the velocity of wave depends on the medium in which wave travels.

As we know that wave speed is given as

v = \sqrt{\frac{\gamma RT}{M}}

so here as the medium of the wave changes the speed of wave also be different so here correct answer will be

b. depends upon the medium in which it occurs

The Doppler Effect provides the equation for the calculation of apparent frequency:

f=fo[vo/(vo-vr)] 

where:<span>
vo=source wave velocity 
vr=relative speed between source and observer 
f=apparent frequency 
fo=source frequency </span>

<span>
The velocity of the doppler wave is 
v=λf</span>

where λ is light wavelength. Hence,

v=λfo[vo/(vo-vr)] 

Based on the equation, we can say that wave velocity will always be defined by one and only one wavelength.

Therefore the answer is letter C.
