Definition
Shock Waves are high-amplitude pressure waves produced when a wave source travels faster than the speed of the waves it generates in a medium.
Why It Matters
It explains sonic booms, explosions, and shock-front physics.
Core Concepts
- The Doppler Effect:
- Bow Waves: V-shaped waves produced by a source moving faster than the wave speed in a medium (e.g., a boat on water).
- Shock Waves: Cone-shaped waves produced by a source moving at supersonic speeds (faster than sound).
- Sonic Boom: The loud sound heard when the “cone” of compressed air from a supersonic aircraft sweeps over an observer.
