3a) The speed of the wave pulse is given by the formula of 0.9(90cm converted into metres)/ 1.69 seconds , which is 0.533m/s when converted to the nearest 3 significant figures.
3b) We found out that when the tension is high, the pulse travels much faster than when the tension is low, leading me into believing that a method to increasing the speed of the pulse without changing the amplitude would be to increase the tension
