Solution :
Given :
Wavelength of the thin beam of light, λ = 50 μm
Distance of the screen from the slit, D = 3.00 m
Width of the fringe, Δy = ±8.24 mm
Therefore, width of the slit is given by :
= 0.000018203 m
= 0.0182 mm
= 0.018 mm
The intensity of light is given by :
, where
Now,
= 0.1854
≈ 0.18
= 2 x0.81
