Question
In young′s double slit experiment, slits are arranged in such a way that besides central bright fringe, three is only bright fringe on either side of it. Slit separation d for the given condition cannot be (if λ is wavelength of the light used) :
Options
A.λ
B.λ / 2
C.2λ
D.3λ / 2
Solution
As path difference d sin θ = nλ ⇒ d = 
As sin θ < 1 so d > nλ, where n is an integer
Therefore d ≠ λ and d ≠
As sin θ < 1 so d > nλ, where n is an integer
Therefore d ≠ λ and d ≠
