Consider a Young's double slit experiment as shown in figure. What should be the slit separation d in terms of wavelength λ such that the first minima occurs directly in front of the slit ( S 1 ) ?

Question

Consider a Young's double slit experiment as shown in figure. What should be the slit separation d in terms of wavelength λ such that the first minima occurs directly in front of the slit ( S 1 ) ?, λ 5 - 2, λ 2 5 - 2, λ 2 5 - 2, λ 5 - 2

Path diff. in front of a slit on screen ∆ = 5 d - 2 d = 2 n - 1 λ 2 (for minima) For 1 s t minima n = 1 d 5 - 2 = λ 2 d = λ 2 5 - 2
