Worksheet 1 Example 3 - Carisa Chan

(a) Calculate the speed of the wave pulse.

Speed = Wavelength/Period
= 90cm/1.69s
= 53.3 cm/s (3 s.f.)

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

Control:

Increase in amplitude:
The speed did not change.

Increase in damping:
The speed did not change.


Decrease in tension:
The speed of the wave changed. It became much slower. Therefore, I conclude that it is possible to change the speed of the wave pulse (of the same width) by changing the tension.
