True or false: A sonic boom occurs only when an aircraft is breaking through the sound barrier. Defend your answer.

To identify: Whether the given statement is true or false.
Answer to Problem 54A
The given statement is false.
Explanation of Solution
Introduction:
Bow waves are produced when the source object travels with the speed greater than the waves, it is producing.
When an aircraft travels with the speed of sound and crosses it, to produce bow waves, then a sonic boom will produce. When it travels continuously with the speed greater than the speed of sound, only then it produces a sonic boom.
Conclusion:
Thus, a sonic boom occurs only when an aircraft is breaking through the sound barrier. This statement is false. When it continuously moves with a speed greater than the speed of sound that is it acts as supersonic aircraft.
