How does the fringe width of interference fringes change, when the whole apparatus of Young’s experiment is kept in a liquid of refractive index 1.3? |
|
Answer» Fringe width, β = Dλ/d => β ∝ λ for same D and d. When the whole apparatus is immersed in a transparent liquid of refractive index n =1×3, the wavelength decreases to λ = λ/n = λ/1.3. so, fringe width decreases to 1/1.3 time. |
