4. The figure below represents the overlapping of a double-Slit with a Single Slit interference patterns, observed on a screen at a distance L from a Coherent light source of 600nm wavelength. If the Single-slit aperture is 50\mu m, the distance between the two slits is 0.40mm, and the separation between two consecutive dark fringes in the double-Slit interference pattern is 3.6mm a) Calculate the distance of the screen from the light source b) Calculate the separation between two consecutive dark fringes in the Single - Slit interference pattern.

Step 1
The formula is given by: d = λL / D where d is the distance between adjacent bright fringes, λ is the wavelength of the light, L is the distance from the light source to the double-slit, and D is the distance between the double-slit and the screen. Show more…

Monochromatic light (λ = 560 nm) strikes a pair of slits at normal incidence, forming the double-slit interference pattern shown on a screen located 2.60 m from the slits. What is the slit separation if the distance between the dashed lines is 16.0 mm?
Vaidik S.
The interference pattern from two slits separated by $0.37 \mathrm{mm}$ has bright fringes with angular spacing $0.065^{\circ} .$ Find the light's wavelength.
1. Light of wavelength 680 nm falls on two slits producing an interference pattern where the fourth order dark fringe is 48 mm from the centre of the interference pattern on a screen 1.5 m away. Calculate the separation of the two slits.
