Question

Derive fringe separation formula for ydse.​

Answer 1

Explanation:

Derive an expression for the fringe width 'y' in Young's double slit experiment. Use X as the wavelength of the monochromatic source, D as the distance of the screen from the slits and d as the distance of separation between the slits.

Answer 2

Answer:

Show that, for small angles (where sinθ≈θ sin θ ≈ θ , with θ in radians), the distance between fringes is given by Δy=xλd Δ y = x λ d . Figure 8. The distance between adjacent fringes is Δy=xλd Δ y = x λ d , assuming the slit separation d is large compared with λ...
