Part of this exercise included an illustration of how sound waves behave at slower than, the same as, and faster than, the speed of sound. Based on what you observed during the exercise, which of the following is TRUE?
When traveling slower than the speed of sound, the sound waves were always behind the sound source.
When traveling faster than the speed of sound, the sound waves were always behind the sound source.
When traveling at the speed of sound, some sound waves remain in front of the sound source, but the majority are behind it.
The frequency of sound chosen dictates whether or not sound waves will be in front of, or behind the sound source.
