Q2. Consider two identical interfering waves with wavelength λ = 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 π/6 rad? Ax = 1/40 m Ax = 1/60 m Ax = 1/20 m Ax = 1/50 m Ax = 1/30 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 π/6 rad?
Ax = 1/40 m
Ax = 1/60 m
O Ax = 1/20 m
Ax = 1/50 m
O Ax = 1/30 m
