Two Graphs of a Wave

Part of the Optics, Waves and Modern Physics section of Coddy's Physics journey. Lesson 19 of 53.

y against x: a photo of the rope. One wave along it is λ.

y against x

y against t: one bit of the rope over time. One wave along it is T.

y against t

Challenge

A graph of y against x shows a wavelength of 0.8 m, and a graph of y against t for one point shows a period of 0.2 s. How fast v does the wave travel?
