Question
Consider two identical interfering waves with wavelength A = 0.4 m travelling in
the positive x-direction. The two waves start at the same time but at different
positions, x1 and x2 from an observer (x1 > x2). What should the path difference,
Ax = x1 - x2, between the starting positions be in order for the two waves to
differ in phase by t/6 rad?
Ax = 1/50 m
O Ax = 1/40 m
O Ax = 1/30 m
O Ax = 1/60 m
O Ax = 1/20 m
