A transverse wave on a string has an amplitude 3A.
A tiny spot on the string is colored Green. As one cycle of the wave passes by, what is the total distance traveled by the green spot?
3 A
6 A
12 A
Answer explanation
The particle moves up from equilibrium line to the peak (3A),
and then back down to the equilibrium (3A), further down from equilibrium line to trough (3A)
and then back up to the equilibrium (3A)
3A + 3A + 3A + 3A = 12 A

As a wave moves through a medium at a speed v, the particles of the medium move in simple harmonic motion about their undisturbed positions.
When the amplitude of the wave triples, the wave speed v ______________.
becomes 3 times bigger
stays the same
becomes one third (1/3)
becomes 9 times bigger
Answer explanation
Wave speeds is only dependent on the properties of the rope, not the amplitude, wavelength or frequency
