Write a story ending with "I liked the novel idea".​

Answer 1

Explanation:

Let 'a' be the width of each slit. Linear separation between n bright fringes, x = nβ = nλD d Corresponding angular separation, θ1 = x D = nλ d Now, the angular width of central maximum in the diffraction pattern of a single slit, θ2 = 2λ a As θ1 = θ2 nλ d = 2λ a ∴ a = 2d n ; where d =
