The diagram shows an object floating in water through which a progressive wave is passing. In time t, the object moves from maximum displacement at a peak of the wave to minimum displacement at a trough and then back to maximum displacement again. Through which vertical distance does the object move in time t?

1. Aone wavelength
2. Btwice the wavelength
3. Ctwice the amplitude
4. Dfour times the amplitude
