In this case, there will be a reversal of phase due to reflection. Let the incident wave be represented by the equation. The reflected wave will have the same magnitude of the amplitude, velocity and wavelength. Due to reversal of phase (i.e., a crest returning as a trough or vice versa) the sign o..
