A plane produces a sonic boom when:
Correct answer: A. Its speed is greater than sound
- A. Its speed is greater than sound
- B. Its sound is much louder
- C. It produces sound of high energy
- D. It produces sound of high amplitude
Explanation
A sonic boom is the shock wave formed when an object travels supersonically (speed > sound) and the pressure disturbances coalesce into a sharp shock, producing the audible boom.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
