This web page provides animations that show the physics of the Doppler effect and the formation of shockwaves from sound waves generated by a moving source. Photos show shockwaves of a bullet, an airplane, and a supersonic land vehicle. Links provide further information.
Editor's Note: A very nice visual to augment teaching the concept of the Doppler Effect for Sound.
