his next step is going to take some skill and some careful observation. The wave speed is associated with the movement of crests and troughs along the medium. Faster waves will have crests that move from the left side of the screen to the right side of the screen in less time; that is the crests move from left to right faster. Set the animation to a low frequency (about 0.1 Hz) and observe the wave speed. It might help to put your finger or a pen cap on a crest and move your finger (or pen cap) from left to right along with the crest. Then repeat for a high frequency (about 1.0 Hz). Make the same observation of wave speed - the speed of the crest moving from let to right across the screen. Does this ten-fold increase in frequency - from about 0.1 Hz to about 1.0 Hz - have any noticeable and appreciable effect upon the wave speed? Explain your answer and discuss your observations.
