Monday, april 2, 2012: hw11: tomorrow night (april 3) at 11:59pm, hw 12: due monday april 16, of ce hours mwf 12:30-1:30. Exam 4: april 17: exam 4 covers chapters 13-16. Longitudinal waves: particle displacement parallel to the wave velocity, no net transport of matter only energy (also true for transverse waves, watch a single particle any one particle just goes back and forth. Transverse wave in a liquid: particle displacement perpendicular to the wave velocity, no net transport of matter only energy (also true for transverse waves, watch a single particle any one particle just goes up and down. Transverse traveling wave y(x, t) = ym sin kx ! With increasing t, the sin curve moves to the right (assuming ) !> 0. Left moving wave: y(x, t) = ym sin kx +!t. Wavelength : distance in x for the wave to repeat. Period : time for one point to.
