They add up.
it is possable for a crest to overlap a trough and they cancel each other out
destructive interference
The overlap of one wave crest with another can result in interference, which can be constructive (additional) or destructive (reductive) depending on the phase of the wave.
Interference does not occur when one wave is brighter than another, and the fainter wave cannot be observed. It occurs when two or more waves overlap.
noise cancelling
When the crest of one wave overlaps the trough of another, this produces destructive interference. If both original waves are equal in amplitude, then nothing will remain. The waves completely cancel out. However, if one waver is larger in amplitude, then there will still be a wave left over after they meet, but it will be smaller. The amplitude of the new wave will be the larger wave amplitude minus the smaller wave amplitude one. The opposite can also occur. If the crests of two waves overlap, then it produces constructive interference (resulting in one larger wave).
If you mean between two positive, or two negative, peaks of an electrical wave, it's the wavelength. If it's a pressure wave, "peak" is usually taken to mean "maximum pressure", so it would be between "peaks".

yes
frequency - number of cycles in one secondamplitude - height of the peakswavelength - distance between peaks (or any other pair of identical points on the wave)
Use the formula v=fλv=Speed of the wave (Light travels about 3x10^8 m/s)λ=wave length (distance from one peak to the next)so by rearranging the formula to v/λ =frequency, you can work out the frequency of the wave by using the distance between peaks (as the wavelength) divided by the speed of the wave.Hope this helps
