Unformatted text preview: 1 Physics 202, Lecture 20 Today’s Topics Wave Motion General Wave Transverse And Longitudinal Waves Wave speed on string Reflection and Transmission of Waves Wave Function Sinusoidal Waves Standing Waves General Waves Wave: Propagation of a physical quantity in space over time q = q(x, t) Examples of waves: Water wave, wave on string, sound wave, earthquake wave, electromagnetic wave, “light”, quantum wave…. Mechanic wave: Propagation of small motion (“disturbance”) in a medium. Physical quantity to be propagated: displacement. Recall: Displacement is a vector. Transverse and Longitudinal Waves If the direction of mechanic disturbance (displacement) is perpendicular to the direction of wave motion, the wave is called transverse wave. If the direction of mechanic disturbance (displacement) is parallel to the direction of wave motion, the wave is called longitudinal wave....
