QuestionAnswer
Wave disturbance that moves through matter and space and carries energy.
Transverse Wave mechanical wave that causes particles in matter to move at right angles to the direction the wave travels
Compressional wave mechanical wave that causes particles in matter to move back and forth along the direction the wave travels
Wavelength distance between one point on a wave and the nearest point moving with same speed and direction.
Frequency number of wavelenghths that pass a given point in one second, measured in hertz.
Law of refection states that the angle the incoming wave makes with the normal to the reflecting surface equals the angle the reflected waves makes with the surface
