Electromagnetic waves also have the property that they interfere. [[Image:MichIntInt.jpg|thumb|Interference from a Michelson Interferometer (courtesy of [http://www.arikah.com/encyclopedia/Interference])]] Like interfering mechanical waves, EM waves can interfere destructively or constructively depending on the phase difference  between the two waves.  In order for this to occur, the light waves must be traveling in the same direction, be of the same wavelength and have “a constant phase with respect to each other” (Serway and Jewett 1177). A picture of EM wave interference is shown at right.
