Physics 110

This is the textbook for the Physics 110 course - The Physics of Sound, Music, and Hearing - at Joliet Junior College. The course is a general-education physical science (with lab) course. In this course, we explore the basic fundamentals of the physics of sound, the perception of sound, and how musical instruments work to create their distinct sounds.
