What is angular fringe width?
When we see an interference pattern due to double-slit interference say, we observe alternate bright and dark fringes of the same sizes. the width of these fringes is called fringe width. angular fringe width is the ratio of fringe width to the distance between source and screen. young’s double-slit experiment uses two coherent sources of light placed at a small distance. it helps to find angular fringe. angular fringe width mathematical equation: θ = nλ d where θ represents angular fringe width, λ represents wavelength, n represents a number of bright fringes, d be the distance between two slits..

How does the fringe width, in Young’s double-slit experiment, change when the distance of separation between the slits and screen is doubled?
In a Young's double-slit experiment, the screen is moved away from the plane of the slits. What will be its effect on the following? (i) Angular separation of the fringes. (ii) Fringe …
In double-slit experiment using light of wavelength 600 nm, the angular width of a fringe formed on a distant screen is 0.1 ∘. What is the spacing between the two slits? Q.
In a Young's double slit experiment, an angular width of the fringe is 0.35$$^\circ$$ on a screen placed at 2 m away for particular wavelength of 450 nm. The angular width of the fringe, when …
Young's double slit experiment and the resulting diffraction pattern. Each bright fringe is identical and has the same width and intensity; The fringes are all separated by …
∴ The angular width of a fringe in Young’s double slit experiment is given by, \(\begin{array}{l}\theta ={{\theta }_{n+1}}-{{\theta }_{n}}=\frac{\left( n+1 \right)\lambda }{d}-\frac{n\lambda }{d}=\frac{\lambda }{d}\end{array} \)
In a double-slit experiment the angular width of a fringe is found to be 0.2° on a screen placed 1 m away. The wavelength of light used is 600 nm. What will be the angular …
