Suppose you are looking at a wave traveling past you. What does wave speed mean, in relation to what you are seeing?

Now how does the figure relate to the wave speed?

I don't think it is complicated so much as requires that you understand the physics somewhat.
ie. how would you normally be able to find out the speed of something - say, a car?

The distance / time = velocity . But I do not jab the time here .
