How frequent this wave cycles, is directly associated to the pitch. Pitch is also described as frequency, as it relates ...

from a wave with zero degrees of phase shift. The t parameter, of course, is time in seconds. If you think about a sine wave, it is really showing a point on a moving and rotating circle.
