Question

Two views of a travelling wave disturbance are shown in the figures on the right. Above is a snap- shot taken at0s. The lower view tracks the displacement of the medi from its equilibrium position at the fixedpo space o as a fme tion of time. The wave dist urbance is in tion of time. The wave disturbance is measured in centimet res. (a) Det he amplitude of the wave disturbance by inspecting the (i) upper 2 and ) lower sketch. ii waveumber quency, and (ii) angular frequency. (b) Determine the () wavleth and (c) Determine theiod fre- d Determine the speed of the wave.
