5. The figure shows a snapshot graph at t = 0 of a sinusoidal wave traveling to the right at 10 m/s.
A) Using the graph, estimate the amplitude of the wave.
B) Using the graph, estimate the wavelength of the wave.
C) Using the given speed, estimate the frequency of the wave.
D) Write an equation to represent the oscillation using a sine function. Your equation should have numerical values for all quantities except x and t.
