Three jet planes traveling faster than the speed of sound produce the shock waves shown in the attached picture. Which plane is traveling with a speed closest to the speed of sound? Explain
When a jet travels faster than speed of sound, sounds from approach source gets interfered with sounds produced due to receding due to Doppler effect.
