a) Calculate the speed of the wave pulse.
Amplitude (A): 6cm
Wavelength (λ): 16cm
90/1.69 = 53.2544cm/s
= 53.3cm/s (3 S.F.)
b) It is possible to change the speed of the wave pulse of the same width by adjusting the tension level (From low to high).
Control (Default setup):
Setup where amplitude increases, speed remains the same. (Time and distance as the constant)
Setup where damping increases, speed remains the same. (Energy is lost)
Setup where tension is reduced, speed is slower. (Distance, wavelength and amplitude changes)
