At a certain point, two waves produce pressure variations
Chapter , Problem 88(choose chapter or problem)
At a certain point, two waves produce pressure variations given by %p1 # %pm sin vt and %p2 # %pm sin(vt $ f).At this point, what is the ratio %pr/%pm, where %pr is the pressure amplitude of the resultant wave, if f is (a) 0, (b) p/2, (c) p/3, and (d) p/4?
