Unformatted text preview: means.) The wave travels a distance of 20 m each second, so its speed is 20 m/s . (Again, no calculation is needed here, but you do need to know what the speed of a wave means.) 31. One side of the sun (the bluer point A) is moving towards us relative to the other side (the redder point B). So the sun is rotating. 35.
