TRAVELING WAVES A wave pulse is a disturbance that propagates through a medium. It transfers energy without transferring matter.

13.3 Wave Motion A harmonic disturbance can set up a sinusoidal wave. The distance from crest to crest, or trough to trough, is called the wavelength, λ.

Longitudinal waves The particles in the medium move parallel to the direction in which the wave travels.

SOUND WAVES As the tines of the tuning forks vibrate back and forth, they begin to disturb surrounding air molecules. These disturbances are passed on to adjacent air molecules by the mechanism of particle interaction. The motion of the disturbance, originating at the tines of the tuning fork and traveling through the medium (in this case, air) is what is referred to as a sound wave.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
