SUMMARY
The discussion centers on the conditions under which shock waves, specifically sonic booms, occur when an object exceeds the speed of sound. The speed of sound in air at sea level is approximately 340 m/s (or 1225 km/h). Shock waves are generated whenever an object travels faster than Mach 1, regardless of the object's overall speed, as long as there are localized areas where the flow velocity reaches Mach 1. The phenomenon is influenced by factors such as temperature, pressure, and the object's velocity relative to the sound waves it produces.
