Transverse - Oscillations of this wave are perpendicular to wave travel, Longitudinal - Oscillations of this wave are parallel to wave travel, Amplitude - Max displacement of a point from equilibrium, frequency - Number of wave cycles per second, Path - Difference in distance travelled between 2 waves meeting at a point is ____ difference, Phase - How much a wave lags or leads another wave, in terms of a fraction of its wave cycle _____ difference, Constructive - Type of interference with a phase difference of 0, Destructive - Type of interference with a phase difference of 180 degrees, Superposition - When 2 or more waves meet, the resultant wave pattern is the vector sum of the individual wave, Superpose - Means combine, waves do this when they meet, Coherent - Waves with the same frequency and a constant phase relationship, Progressive - A wave that does transfer energy is a __________ wave, Hertz - Unit of frequency, 300000000 - Speed of all EM radiaiton in m/s,
