April 29, 2008 Physics 40B Lecture 8 2 Mechanical Waves Waves as means of propagation of energy and momentum without propagation of matter Requires medium to propagate in which has restoring force and inertial mass Electromagnetic waves are different; propagate in vacuum Examples of Mechanical Waves Water waves Seismic Waves Sound Waves Waves on wire, rope, spring, in solids Moving or traveling waves are propagating disturbances (“wiggles”) in medium
April 29, 2008 Physics 40B Lecture 8 3 Types of Waves Transverse (in solids): Matter moves perpendicular to propagation direction (crests & troughs) Longitudinal (in fluids/solids): Matter moves parallel to propagation direction (compression & rarefication) Surface Waves in Liquid: transverse & longitudinal motion of particles Have definite velocity (speed) of propagation that depends on medium

### What students are saying

• 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.
