Phase
As applied to waves of electromagnetic radiation, phase is the relative measure of the alignment of two wave forms of similar frequency. They are said to be in phase if the peaks and troughs of the two waves match up with each other in time. They are said to be out of phase to the extent that they do not match up. Phase is expressed in degrees from 0 to 360.
