ll. So, what does affect the speed of a wave pulse? LaterI we'll return to the issue ofwhy the flick speed doesn't control the pulse speed. But rst, let's nd what does control the pulse speed. A. Suppose you want to inerease the tension in the spring. I. How could you do it'}I 2. How do you think increasing The tension affects the pulse speed, if at all'?I Explain your reasoning. B. Now imagine thickly painting the spring with heavy paint, Thereby increasing its mass per length. Do you expect this paintjoh to increase or decrease the pulse speedI other things being equal, or do you expect the pulse speed would he unchanged? Explain your reasoning. '13:? Consult on instmctor before you proceed. T . C. A careful derivation shows that The pulse speed is 1': _ Boston _ , where linear mass moor mass dEMIIJa' density is mass per length. Does this equation agree with your answers To parts A and E
