Lowest point of a wave?

Explanation:
Waves have high points called crests and low points called troughs. The lowest point the wave reaches is the trough. The amplitude is how tall the wave is from its resting position, not the lowest point, and the wavelength is the distance from one repeating point of the wave to the next. So the lowest point being the trough is the correct idea.
