Chapter 16 talked a lot about waves and sound. What is a wave? According to physics.tutorvista.com, “a wave can be described as a disturbance that travels through a medium from one location to another location.” As stated in the physics textbook, there are two common features to all waves. These common features are a wave is a traveling disturbance and carries energy from one place to another. There are two main types of waves. The first is called a transverse wave. Transverse waves occur when a disturbance creates oscillations perpendicular to the direction of the travel of the wave. The second is called a longitudinal wave. Longitudinal waves occur when the disturbances are parallel to the direction of propagation. What is sound? According
