A) it explodes
B) it produces shock wave which is received as the bang
C) its wings vibrate so violently that the bang is heard
D) the normal engine noise undergoes a Doppler shift to generate the bang
Correct Answer: B
Solution :
The sonic boom associated with the passage of an aircraft is the sound wave resulting from the degradation and merging of the shock wave expansion wave pair produced by the passage of a supersonic aircraft. Shock waves are characterized by a sudden change in the characteristics of the medium as a positive step function. A shock wave travels through the medium at a higher speed than a normal wave.You need to login to perform this action.
