Can anyone help me with this physics question?

Question

The distance between two successive maxima of a transverse wave is 1.40 m. Eight crests, or maxima, pass a given point along the direction of travel every 7.0 s. Calculate the wave speed in m/s.

Answer 1

8 crests means 7 wavelengths (draw it out if you need to prove it to yourself. So a total of 7 * 1.40 m has passed the given point in 7.0 s.

Speed is the total distance over the total time. I'm sure you can do the division. -trickshottim
