a) Two snapshots of a wave moving to the right are superimposed asshown below. The snapshots are taken at t=0s and t=0.1s. Estimatethe period, frequency, amplitude, wavelength and velocity of thiswave. At the position x=2, what is the displacement at each of thetimes shown?
b) Given the wave form seen below with the horizontal axismeasuring time in seconds, one of the component waves that makes upthis wave is 50Hz, what is the other? Explain your reasoning.
