When an object is moving the waves in front of it (sound, light, whatever) get compressed and the waves behind it are stretched apart. so in a race cars case, the compressed waves make a higher pitched noise and vice versa

The pitch is higher as it approaches and then becomes lower the moment it passes.

The characteristics of standing waves allows to find the result for the speed of the wave is:

The speed wave is: v = 10 m / s

The wave is a way of transmitting energy without mass displacement, , in the attachment we can see a diagram of the standing wave.

Each cycle corresponds to half a wavelength, they indicate that the frequency is 2.50 Hz and there are three cycles, so the wavelength is:

L = $n \frac{\lambda}{2}$
