PHYS 2101 Lecture : Lecture 32
Document Summary
Hw #12 is also posted and due when we get back: test #4 is the tuesday (april 17) after spring break (after only 2 lectures) Transverse: displacement of particle is perpendicular to the direction of wave propagation. Longitudinal: displacement (vibration) of particles is along same direction as motion of wave. It will cover the topics of fluids, gravitation, oscillations, and waves. 16 - waves i & ii and a bit of review. Here, two sinusoidal waves with same wavelength travel in opposite directions moving sin + sin = 2 sin 1. ) & = kx + t y1(x,t) = ym sin kx t. + y2 (x,t) = ym sin kx + t ytot (x,t) = ym sin kx t. ) cos t( amplitude oscillating term at position x in time. Amplitude is zero when: kx= n n = 0,1,2,3, . Amplitude is max when: kx= (n+1/2) n = 0,1,2,3, x = n.
