Homework Statement
I have two plane waves, one of the form: 4 sin(20t + (pi/3)x + pi), and the other one: 2 sin(20t +(pi/4)y + pi) .. with the same frequency and vibrations in the z direction ..
I am asked to find the resultant wave equation at x = 5 and y =2
Homework Equations
maybe x = r costheta
The Attempt at a Solution
I have the answer to this question as 2.48sin(20t-0.2pi), I know I can't just substitute the x and y in the waves and simply add them .. and unfortunately the book doesn't discuss such situation .. I would appreciate any hints and suggestions .. Thanks in advance
