Question

The fringe widths are found to be ω 1 and ω 2 respectively if a Young's double slit experiment is performed in medium of refractive index n 1 and n 2 respectively. The correct statement is, ω 1 > ω 2 if n 1 > n 2, ω 1 > ω 2 if n 1 n 2, ω 1 = ω 2 if n 1 n 2, ω 1 ω 2 = n 1 n 2

Fringe width of Y.D.S.E. in a medium is given by, ω = D λ d n For a particular Y.D.S.E. set up and light, D , d & λ remains constant, therefore ω ∝ 1 n So, we can conclude, if n 2 > n 1 , ω 1 > ω 2 .
