Easy

When an aeroplane attains a speed higher than the velocity of sound in air,a loud bang is heard. This is because

  • A
    It explodes
  • B
    It produces a shock wave which is received as the bang
  • C
    Its wings vibrate so violently that the bang is heard
  • D
    The normal engine noises undergo a Doppler shift to generate the bang
