Answer:
0.001 m or 1 mm
Explanation:
Parameters given:
Wavelength of light, λ = 500 nm = [tex]500 * 10^{-9} m[/tex]
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:
[tex]y = \frac{2 * 500 * 10^{-9}}{0.001}[/tex]
y = 0.001 m = 1 mm
Adjacent dark spots are separated by a distance of 1mm.
