Worksheet 1 Example 3 - Teoh Yun

a) Calculate the speed of the wave pulse.

90÷1.69 = 53.3 (3 s.f.)

Speed: 53.3 cm/s

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

Yes, it is possible only when the tension is adjusted.

[At first (No changes made)]

[Change in Amplitude (Higher amplitude)]

[Change in Amplitude (Lower amplitude)]

[Change in Tension]
