Explore sketches, drawings, and illustrations that simplify ideas related to Sound.

Sonic Boom illustration: a series of increasingly fast planes flying in the sky is shown from left to right, along with their position in relation to the sound shockwaves produced as the air in front of each plane is compressed. The plane on the left travels slower than the speed of sound and is thus behind its shockwaves. In the middle, the aircraft travels at the speed of sound and the shockwaves are shown bunching up near the nose of the plane. On the right, the supersonic, speedy aircraft surpasses the speed of sound creating a loud boom to the delight and / or fright of those on the ground nearby.
