wavelength the distance between one point on a wave and the nearest point moving with the same speed and direction.
frequency the number of wavelengths that pass by a point each second
law of reflection the angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal
refraction the change in direction of a wave when it changes speed as it travels from one material to another
diffraction bending of waves around an object
mechanical needs matter:matter ex;earthquake, sound
electromagnetic needs no matter;space ex;light or heat
