    Answer:

    0.001 m or 1 mm

    Explanation:

    Parameters given:

    Wavelength of light, λ = 500 nm = 500 * 10^{-9} m

    Distance between slits, d = 1 mm = 0.001 m

    Distance between slit and screen, x = 2 m

    The distance between two adjacent dark spots on a screen due to diffraction of light is given as:

    y = xλ/d

    Therefore:

    y = \frac{2 * 500 * 10^{-9}}{0.001}

    y = 0.001 m = 1 mm

    Adjacent dark spots are separated by a distance of 1mm.
