Example 3a
The speed of the wave pulse is 90/1.69cm/s which is 53.3cm/s to 3 significant figures.The speed in metres per seconds would be 0.533m/s to the nearest 3 significant figures.
Example 3b
When the tension is high,the pulse takes a significantly shorter time to travel the length than when the tension is low.Therefore,it is possible to change the speed of the wave pulse by adjusting its tension.
