Understanding Speed of Sound
The speed of sound, also known as Mach 1, is approximately 767.269148 miles per hour (MPH) at sea level and 20°C (68°F). This speed varies based on:
- Temperature: Sound travels faster in warmer air
- Altitude: Speed decreases at higher altitudes
- Medium: Travels faster through liquids and solids than air
Common Applications
Understanding speed of sound is crucial for:
- Aviation and aerospace engineering
- Sound barrier calculations
- Military aircraft design
- Meteorological measurements
