What is the equation for the superposition of 2 waves?
The Attempt at a Solution
Displacement of the first wave is D1 = Asin(k1x - ω1t)
Displacement of second wave is D2= Asin(k2x - ω2t)
Add together: D1 + D2 = 2Acos[(k1-k2)x/2 - (ω1 - ω2)t/2]*sin[(k1 + k2)x/2 - (ω1 + ω2)t/2]
But this isn't in terms of what the problem is asking! Help, can the form be changed somehow?
Is there a way to reduce the k1 and k2 so that it is in that form?
