A progressive wave on a wire has a frequency of 10Hz. Two points on the wire, separated by a
distance of 0.25 m, have a phase difference of 22.5°.
What is the maximum speed of the wave?

The maximum wavelength, and hence speed, will occur when the phase difference occurs within a single period. What is the wavelength here, assuming that? Once you have the (maximum) wavelength, calculate the maximum speed (v=frequency x wavelength).
