In transverse waves, the particles of the medium vibrate ... The angles of incidence and angle of reflection are measured between the wave direction and the normal – an imaginary line drawn ...

That is, each of the plane waves experiences a different strength of reflection ... is reflected by an air–glass interface and its transverse position is measured with a calibrated split ...

It travels as a transverse wave. Unlike a sound waves ... When measuring the angle of incidence, i, or angle of reflection, r, it is important to place the zero line of the protractor along ...
