Number extra waves received from each side:
n = +- u/λ
where
u= speed of the observer
λ = Wavelength of sound
Number of beats:The number of beats is given by the difference between number of extra waves received on either sides.

Two sound sources fixed at a given distance apart are emitting sound e...
To find the wavelength of sound emitted by each source, we need to know the frequency of the sound and the speed of sound in the medium.

Let's denote the distance between the two sound sources as d.

The wavelength of sound can be calculated using the formula:

wavelength = speed of sound / frequency

Assuming the speed of sound in the medium is constant, we can calculate the wavelength for each sound source using the given frequency.

However, since the frequency of the sound is not provided in the question, we cannot determine the wavelength.
