Figure \(\PageIndex{2}\): Single-slit diffraction pattern. (a) Monochromatic light passing through a single slit has a central maximum and many smaller and dimmer maxima on either side. The central maximum is six times higher than shown. (b) The diagram shows the bright central maximum, and the dimmer and thinner maxima on either side.
Single-slit diffraction is the most straightforward experimental setup where diffraction effects can be observed. When light passes through a slit whose width is on the order of the wavelength of light, a distinct diffraction pattern is observed on a screen that is kept at a certain distance from the slit.
Practice Problems on Single Slit Diffraction. Q1: A single-slit diffraction pattern is formed on a screen 2 meters away. If a light of wavelength 500 nm produces the first minimum at an angle of 30 degrees, what is the width of the slit? Q2: Light with a wavelength of 600 nm passes through a single slit and produces a diffraction pattern.
Graph and image of single-slit diffraction. As an example, an exact equation can now be derived for the intensity of the diffraction pattern as a function of angle in the case of single-slit diffraction. A mathematical representation of Huygens' principle can be used to start an equation.
Figure 1 shows a single slit diffraction pattern. Note that the central maximum is larger than those on either side, and that the intensity decreases rapidly on either side. In contrast, a diffraction grating produces evenly spaced lines that dim slowly on either side of center. Figure 1. (a) Single slit diffraction pattern.
Discuss the single slit diffraction pattern. Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings. Figure 27.21 shows a single slit diffraction pattern. Note that the central maximum is larger than those on either side, and that the intensity decreases ...
Diffraction through a Single Slit. Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings, which we discussed in the chapter on interference. Figure 4.3 shows a single-slit diffraction pattern. Note that the central maximum is larger than maxima on either side ...

The central maximum is six times higher than shown. (b) The diagram shows the bright central maximum, and the dimmer and thinner maxima on either side.
Second, it encounters a thin slit that is a little bit smaller than the width of the beam. Naturally a single-slit diffraction pattern appears on the screen. And third, the beam encounters only a sliver that has the same dimensions as the single slit, so that the outer edges of the beam go past the edges of the sliver.
Single Slit Monochromatic Diffraction Pattern. The diffraction pattern of light passing through a single slit is a series of light and dark fringes on a screen. The bright fringes are areas of maximum intensity, produced by the constructive interference of each part of the wavefront as it passes through the slit
Figure 1. (a) Single slit diffraction pattern. Monochromatic light passing through a single slit has a central maximum and many smaller and dimmer maxima on either side. The central maximum is six times higher than shown. (b) The drawing shows the bright central maximum and dimmer and thinner maxima on either side.
In the single-slit diffraction experiment, we can observe the bending phenomenon of light or diffraction that causes light from a coherent source to interfere with itself and produce a distinctive pattern on the screen called the diffraction pattern. Diffraction is evident when the sources are small enough that they are relatively the size of ...

The diffraction patterns were taken with a helium-neon laser and a narrow single slit. The slit widths used were on the order of 100 micrometers, so their widths were 100 times the laser wavelength or more. A slit width equal to the wavelength of the laser light would spread the first minimum out to 90° so that no minima would be observed.

The central maximum is six times higher than shown. (b) The drawing shows the bright central maximum and dimmer and thinner maxima on either side.
Figure \(\PageIndex{4}\): Single-slit diffraction patterns for various slit widths. As the slit width a increases from a=λ to 5λ and then to 10λ, the width of the central peak decreases as the angles for the first minima decrease as predicted by Equation 4.2.1.
Note carefully that the right side of double slit equation is the product of I m and two factors. (1) The interference factor is due to the interference between two slits with slit separation d. (2) The diffraction factor is due to diffraction by a single slit of width a. I(θ)=I mcos2β sinα α! " # $ % & 2 (double slit) β= πd λ sinθα= πa
The single slit. When light passes through a single slit whose width w is on the order of the wavelength of the light, then we can observe a single slit diffraction pattern on a screen that is a distance L >> w away from the slit. The intensity is a function of angle.
Single-slit diffraction: When a light wave passes through a narrow single slit and strikes a screen, a diffraction pattern is formed. The pattern consists of a central bright fringe (maximum) surrounded by alternating bright and dark fringes (maxima and minima).
A student investigates the interference patterns produced by two different diffraction gratings. One grating used was marked 100 slits / mm, the other was marked 300 slits / mm. The distance between the grating and the screen is measured to be 3.75 m.The student recorded the distance between adjacent maxima after passing a monochromatic laser ...
