Question

Speed of supersonic Aircraft is:-

• A. Below speed of sound.
• B. Equal to speed of sound.
• C. More than speed of sound.
• D. Equal to speed of light.

Answer 1

The correct option is C More than speed of sound.

Vehicles that fly at supersonic speeds are flying faster than the speed of sound. The speed of sound is about 768 miles per hour (1236 kilometers per hour) at sea level. These speeds are referred to by Mach numbers. The Mach number is the ratio of the speed of the aircraft to the speed of the sound. Flight that is faster than Mach 1 is supersonic. Supersonic includes speeds up to five times faster than the speed of the sound, or Mach 5
