trough
Measuring a wave from crest to trough in the verticaldirection will give the amplitude of the wave. It's called the peak to peak value (as it is is a measure of the distance from the positive peak to the negative peak -- the crest and trough). Measuring the wave in the horizontal direction from a crest to a trough will result in half a wavelength.Picture a water wave frozen on the surface of a pond. The distance (verticaly) from the bottom of a trough to the top of a crest is the amplitude of that wave. A measure of the distance (horizontally) from the bottom of a trough to the top of a crest is half the wavelength of the wave. (Note that athe use of "bottom of a trough" and "top of a crest" might seem redundant or even nonsensical, but is applied here in the hopes of clarity.)
