What is happening to a sound wave when the pitch increases and the sound source is in motion?

Arcadiouse:

The pitch of a sound is related to the frequency of the sound wave...higher pitch = greater frequency. If a sound source is moving towards you, the wavelength is shortened. If the sound source is moving away from you, the wavelength is lengthened.
