Diffraction gratings are commonly used for spectroscopic dispersion and analysis of light. What makes them particularly useful is the fact that they form a sharper pattern than double slits do. That is, their bright fringes are narrower and brighter while their dark regions are darker.

Diffraction gratings work through multiple-slit interference. When white light travels through a diffraction grating, an interference pattern will show up on the screen. As we have learned, the location of bright and dark spots on the screen depends on the wavelength of the light.

From this, and further calculations, it can be seen that different colours will diffract through a larger or smaller angle depending on their wavelength (or more accurately their frequency). So white light that is shone through a diffraction grating will have the colours separated, as shown in the diagram below:

(a) Light passing through is diffracted in a pattern similar to a double slit, with bright regions at various angles. (b) The pattern obtained for white light incident on a grating. The central maximum is white, and the higher-order maxima disperse white light into a rainbow of colors.

If a beam of white light passes through a diffraction grating with vertical lines, the light is dispersed into rainbow colors on the right and left. If a glass prism disperses white light to the right into a rainbow, how does the sequence of colors compare with …

2020年4月1日 · In this paper, 10 monochromatic lights uniformly selected from the white light spectrum are subjected to grating diffraction. One convert each RGB value and use the Fraunhofer diffraction light intensity formula to obtain the relative intensity at a specific diffraction angle position, taking θ = 2° as an example.
Find the angular width of the first order visible spectrum produced by a plane grating with 600 slits per millimeter when white light falls normally on the grating. Do the first and second order spectrum overlap? What about second and third order spectra? Does your answer depend on the grating spacing? No. m λ where m = 0, ± 1, ± 2,...

2013年6月26日 · White light is directed toward a diffraction grating and that light passes through the grating, causing its monochromatic bands appear on the screen. Which color will be closest to the central white? Three discrete spectral lines occur at angles of 10.1°, 13.7°, and 14.8° respectively in the first order spectrum.
