Document Summary
Free to move through space (search phet travelling simulation online) Particles oscillate in place as waves moves" forward (imagine the wave" in a crowd at a sports game) Any movement of a particle which is displaced by a wave can be represented by a sinusoidal function y = a sin . = angular frequency k = wave vector. + or - depending on direction of travel. Helpful de@initions/equations - (bolded were highlighted as important in lecture) T = period = time for one cycle. The frequency of the wave, number of cycles per unit time. For this, we can write equivalent representations y = a sin t y = a sin 2 f t y = a sin(2 /t) t. = 2 f = angular frequency. For this, we can write equivalent representations y = a sin (k x) y = a sin ((2 / )x)
