A .22 caliber bullet is fired from a rifle. The schlieren optical system images different air pressures with different colors of light. The lack of a bow wave in front of the bullets shows that the bullet is moving slower than the speed of sound. This image freezes the motion by using a high speed flash with a duration of 1/2,000,000th of a second | |
