Question:
In double-slit experiment using light of wavelength 600 nm, the angular width of a fringe formed on a distant screen is 0.1^o. What is the spacing between the two slits?

Answer:

It is given that,

Wavelength of light used, λ = 6000 nm = 600 × 10 ^-9 m

Angular width of fringe, θ = 0.1° = 0.1 x ¶/180 = 3.14/1800 rad

Angular width of a fringe is related to slit spacing (d) as: d = λ/θ = 600 x 10^-9/3.14/1800 = 3.44 x 10^-4 m

Therefore, the spacing between the slits is 3.44 x 10 -4 m.
