What would be the angular separation between the consecutive bright fringes in Young's double slit experiment with blue green light of wavelength The separation between the slits is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Given, in Young's double-slit experiment, the wavelength of light(λ)=500nmthe separation between slits(d)=1·0×10-3mIn the above figure,θ=angles fringe widthsinceθis a small angle, thereforeθ≃tanθ=yD=λDdD=λdθ=4×10-7m1·0×10-3m=4×10-4rad.
