A plane wave is incident obliquely on the two slits of a Young's double-slit experiment. The incidence angle is 0.01 rad, the screen distance is 2 m, and the geometry is such that the central maximum shifts in the positive-y direction. Using the small-angle approximation, find the magnitude of the shift in centimetres.
