Exam 14: Thunderstorms

Sonic booms are produced when an aircraft exceeds the speed of light at the altitude at which it is flying. The aircraft compresses the air, forming a shock wave that trails out as a cone behind the aircraft. Along the shock wave, the air pressure changes rapidly over a short distance. The rapid pressure change causes the distinct boom.
