The equations predict that substantial reflection will occur when a wave 

 passes from deep water to shallow water, and also when a wave passes from 

 shallow water to deep water. It is assumed that no energy loss occurs, 

 and that a single incident wave splits into a single reflected wave and 

 a single transmitted wave. Taking E- as the wave energy of the incident 

 wave, E r as the wave energy of the reflected wave, and E, as the wave 

 energy of the transmitted wave,
