It should be mentioned that each wave-energy is calculated 

 independently ; and a test of the accuracy of the calculations 

 is afforded by the condition that the energy of the incident 

 wave must be fully accounted for. That is, since, in every 

 case the incident wave (either A or B) is taken as unity, the 

 sum of all the others must be unity.
