Example 3 — Lim Hao Yang, Shawn Lim, Sun Jie Min

Calculate the speed of the wave pulse

Distance = 0.90 m
Time = 1.69 s

Speed = 0.90 m / 1.69 s = 0.533 m/s (3 sf)

Is it possible to change the speed of the wave pulse (of the same width)?

Yes. By changing the tension of the string.
When compared to the original wave, the two set-ups has different speed.

Changing the amplitude of the wave will not result in faster speed, only greater displacement.
