Problem C18:
One source produces a wave that varies in time as
y1=A sin(ωt) at a certain position. Another
source produces a wave that varies in time as
y2=-A cos(ωt + (n1/n2)π)
at the same position. What is the net amplitude at this position
due to the two sources if they are coherent? If the displacement is:
y(t)=y1+y2=
√ n3
A sin(ωt + φ),
what is n3? Note that n1, n2 and
n3 are unitless.
