- Mach number: The ratio of the speed of an object to the speed of sound is called the Mach number.
\(Mach~number = {speed ~ of~object \over speed ~of ~sound}\)
EXPLANATION:
If Mach number = 1
\(Mach~number = 1={speed ~ of~object \over speed ~of ~sound}\)
speed of object = speed of sound
This speed of an object (Mach number = 1) is also known as transonic speed.
So the correct answer is option 1.
Additional Information
Mach numbers < 1 ⇔ Subsonic flow;
Mach numbers > 1 ⇔ Supersonic flow.
