**[SOLVED] Wave Motion**

**1. Homework Statement**

A transverse wave on a string is described by the following wave function.

y = (0.115 m) sin [(x/10 + 3t)]

(a) Determine the transverse speed and acceleration at t = 0.240 s for the point on the string located at x = 1.70 m.

(b) What are the wavelength, period, and speed of propagation of this wave?

**3. The Attempt at a Solution**

I have solved the whole problem up to part B) where it says what is the speed of propagation of this wave?

I am not sure what is looking for me to find. I looked up wave propagation and it said, any of the ways in which a wave travels through a medium. I still can't figure out what I am trying to find, so if someone could explain what exactly it is looking for and how to go about it I would be grateful. Thanks
