Supersonic speed:
- Supersonic speed is the speed of an object that exceeds the speed of sound.
Mach number:
- It is defined as the ratio of the speed of the object to the speed of sound.
\(⇒ M=\frac{u}{v}\)
Where M = Mach number, u = speed of the object, and v = speed of sound
EXPLANATION:
- The Mach number is given as,
\(⇒ M=\frac{u}{v}\) -----(1)
Where M = Mach number, u = speed of the object, and v = speed of sound
- For the supersonic speed, the speed of the plane will be more than the speed of sound.
⇒ u > v -----(2)
Bu equation 1 and equation 2,
⇒ M > 1
- Hence, option 2 is correct.
