A muscle can't get longer by itself. There needs to be another muscle

I assume you are talking about the vertical distance: in that case, the answer is 0.6 m.
In fact, the wave's amplitude is the vertical distance between a crest of the wave and a trough. For the wave in the problem, this distance is equal to 0.6 m, therefore the amplitude of the wave is exactly 0.6 m.
