sound source moves either toward or away from the listener, or when the listener moves either
toward or away from the sound source
Wave motion Correct Answer: How does sound travel through a medium?
Sound Correct Answer: In the study of physics, what is defined as a range of compression-wave
frequencies to which the human ear is sensitive?

Pitch Correct Answer: Which term is used to describe the frequency of a sound?
Intensity Correct Answer: What is a measure of the sound energy of a wave?
Loudness Correct Answer: What is the sensation the intensity (and sometimes frequency) the
sound wave produces on the ear?

reflected several times to cause what is known as what?

undesirable response or the degradation of a wave referred to as?
Noise Correct Answer: What is the most complex sound wave that can be produced?

186,000 miles per second in space?
7.5 Correct Answer: How many times in one second can a light beam circle the earth?
