A sinusoidal wave is propagating along a stretched string that lies along the x-axis. The displacement of the string as a function of time is graphed in the figure for particles at x = 0 and at x = 0.0900 m

You are told that the two points x = 0 and x = 0.0900 m are within one wavelength of each other. If the wave is moving in the x-direction, determine the wavelength


Determine the wave speed.

If instead the wave is moving in the x-direction, determine the wavelength.

Determine the wave speed
