The lowest point on a Sound or light wave is called a trough.

A 'trough' is the lowest point
The crest of a wave is its highest point, as opposed to the trough of a wave, which is its lowest point.
Both are ways to transport energy from point a, to point b. Both sound and light waves have a speed, wavelength and frequency. Both can be diffracted, reflected and refracted, as those are properties of waves.
Sound is a longitudinal wave and a light wave is a transverse wave. Sound requires a medium to travel through but light can propagate without any medium.
