In a Young's double slit experiment, each of the two slits A and B, as shown in the figure, are oscillating about their fixed center and with a mean separation of 0.8 ~mm . The distance between the slits at time t is given by d=(0.8+0.04 t) mm , where =0.08 rad s ⁻¹ . The distance of the screen from the slits is 1 ~m and the wavelength of the light used to illuminate the slits is 6000 Ã… . The interference pattern on
