Question

multiple choice question
shock waves are the result of a plane that is flying at the ______ and the sound waves it makes pile up on one another.
fundamental frequency
speed of light
plane overtone
speed of sound

Explanation:

When a plane flies at the speed of sound, the sound waves it emits cannot move ahead of the plane. As a result, these sound waves pile up on one another, creating shock waves. The fundamental frequency is related to the lowest frequency of a periodic waveform. The speed of light is much faster than the speed at which shock - wave - related phenomena occur in this context. A plane overtone is not relevant to the formation of shock waves due to a plane's speed.

Answer:

speed of sound
