2. Consider the following two plots of a one dimensional harmonic wave: f (cm) f vs .r. f = 0 4 f (cm) f \\'s t. .r = 0.5 in :1) Determine the period' wavelength. amplitude, speed, and direction (left or right) of the wave, then write down a function describing the wave. 1)) Sketch f vs t for the point :r = 2.5 n] and sketch 3" vs :1? at a time t = 1.5 s
