   1. The problem statement, all variables and given/known data
   Having two identical waves, knowing how much they're out of phase with each other, how can I know the amplitude of the resulting wave (as a factor of the original amplitude)?
   
   
   2. Relevant equations
   
   
   
   3. The attempt at a solution

   Write down two wavw equations, say
   A1 = Ao(sinwt + phy1) and A2 = Aosin(wt + phy2)
   Add them to find the amplitude of the resultant wave.
