Q$2$: The drawing shows a graph of two waves traveling to the right at the same speed.

$($a$)$ Using the data in the drawing, determine the wavelength and the amplitude of each wave.

$($b$)$ The speed of the waves is $4\frac{m}{s}$; calculate the frequency of each one.

$($c$)$ What is the maximum speed for a particle attached to each wave?
