Question
The SI unit of speed of sound is ____.
- m/s
- m/s2
- m2/s
- m
Hint:
The SI unit of speed of sound is m/s.
The correct answer is: m/s
- The speed of sound can be represented by a meter per second.
- It shows the distance traveled by the sound wave in a second.
- So the speed of sound can be written as m/s in SI units.
