Diffraction Grating, focal length of lens | Physics Forums

Light from infinity strikes a diffracting grating normally with 600 lines per mm. The emitted light then passes through a lens to project visible light (400-800 nm) spectrum onto a screen that is 50mm, just enough to cover it. Find the focal length of the lens. Did I read that right: The screen is w

To find wavelengths of prominent spectral lines of Mercury

A spectral line is like a fingerprint that can be used to identify the atoms, elements or molecules around us. Diffraction Grating is optical device used to learn the different wavelengths or colours contained in a beam of light.

Grating - Wikipedia

Grating elements can have luminances other than that of sharp-edged bars. If the graph of a grating is sinusoidal (see top panel in the illustration), the grating looks like a set of blurry light and dark bars and it is called a sine-wave grating. Sine-wave gratings are used extensively in optics to determine the transfer functions of lenses. A

Our diffraction grating is a transparent sheet of plastic with dark lines on it spaced 1/500 of a millimeter (2µm) apart. Light waves pass through the spaces between the lines, called slits, and interfere with waves going through adjacent slits to produce bands of light or dark where the interference is constructive or destructive.

A slit grating is a grating provided by slits in a solid framework, where as a phase grating has a multitude of fine, parallel grooves cut into a small sheet of glass or metal. The interference produced by a reflection grating is in reflected light, whereas the interference produced by transmission grating is then transmitted light.

A Simple DIY Spectrophotometer: 8 Steps (with Pictures)

A spectrophotometer measures the amount of light that a certain sample absorbs. The basic principle: A beam of light passes through a prism or diffraction grating. Out of the resulting spectrum, a certain (range of) wavelength(s) gets selected by sending the light through a slit. The light passes through the sample and hits a detector.

Diffraction grating - Wikipedia

Diffraction grating - Wikipedia

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.
