![]() ![]() Fraunhofer diffraction: Using this slit as a reference, we can see that all of the light rays are parallel.Incoming waves don’t go in a straight line. Fresnel diffraction: There are fixed distances between the slit and the light source and screen.The slit width should be equal to or less than the wavelength of the light that is being reflected.Monochromatic light should be used as the primary source of illumination.⇒ Angular width of central maximum = 2θ = 2λ/a Conditions for diffraction The width of the central maximum is simply twice this value On either side of the center, there are two minima, which are separated from each other by a distance which is equal to the width of the central maxima. Since for every ray originating from a point on the slit has a corresponding ray at a distance a/2 that produces destructive interference, destructive interference occurs at the angle θ = sin-1(λ/a). To create a dark fringe, the path difference must be out of phase by λ /2 (where λ is the wavelength of light). Any arbitrary pair of rays at a/2 distance can be taken into account. Think about a pair of rays coming from a/2 distances.įor this let us consider a ray coming from the bottom of the slit and another from the middle of the slit, both at a distance of a/2 from one another. Divide the slit into equal-width of a/2 zones. We’ll start with the condition of the black fringes to understand the pattern. Single slit diffraction: formulaįor any screen point, we will measure a/2 lengths from its center to determine the angle of the screen. The intensity is influenced by the angle at which it is viewed. The diffraction pattern can be viewed on a screen at a distance L from the slit, where L > a. ![]() When light passes through a single slit with a width (a) on the order of the wavelength of the light, we can witness single slit diffraction. Reciprocal trig ratios (article) | Khan Academy.Diffraction, which is the bending of light around the margins of an opening or a barrier and it is displayed by all sorts of waves.
