Koh Su En - Worksheet 1 Example 3

(a) Calculate the speed of the wave pulse.

Velocity = wavelength / period

16cm/0.3s = 53.3 cm/s (3 S.F)

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

Change in Amplitude:

Result: No change in Velocity

Change in Damping:

Result: No change in Velocity

Change in Tension:

Result: Change in Velocity as wavelength is shorter.

Conclusion: It is possible to change the speed of the wave pulse by changing the tension.
