Consider two identical interfering waves with wavelength A = 0.2 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?

Consider two identical interfering waves with wavelength A = 0.2 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 1/40 m
O Ax = 1/20 m
O Ax = 1/30m
O Ax = 1/60m
O Ax = 1/50 m
