Question
A transverse wave, traveling along the positive x-axis, given by y = A sin(kx - ωt) is superposed with another wave traveling along the negative x-axis given by y = - A sin(kx + ωt). The point x = 0 is
Options
A.a node
B.an anitnode
C.neither a node nor an antinode
D.a node or antinode depending on t.
Solution
At x = 0, y1 = A sin (-ωt) and y2 = - A sinωt ; y1 + y2 = - 2A sin ωt (antinode)
