Waves Doppler Effect

In class we leared about Waves and The Doppler Effect. The Doppler Effect is a varation in the frequency when there is relative motion between the source of the frequency and the observer. If the source is approching there will be a higher frequency and if it is Receeding there is a lower frequency. An example of The Doppler Effect is the fire truck siren, which was talked about in class.
