A diffraction grating with 2000 lines per centimeter is used to measure the wavelengths emitted by a hydrogen gas discharge tube. (a) At what angles will you find the maxima of the two first-order blue lines of wavelengths 410 and 434 nm?

- 4.5: Diffraction Gratings
Diffraction gratings are key components of monochromators used, for example, in optical imaging of particular wavelengths from biological or medical samples. A diffraction grating can be chosen to specifically analyze a wavelength emitted by molecules in diseased cells in a biopsy sample or to help excite strategic molecules in the sample with ...

A diffraction grating is used to produce narrow bright fringes when laser light is diffracted through it. Just like for single and double-slit diffraction the regions where constructive interference occurs are also the regions of maximum intensity; Their location can be calculated using the diffraction grating equation; Where: n is the order of ...
Consider a spectrometer based on a diffraction grating. Construct a problem in which you calculate the distance between two wavelengths of electromagnetic radiation in your spectrometer.
Diffraction gratings are an optical tool that are made up of many many slits side-by-side, sometimes thousands of slits per millimeter, and allow for the diffraction of light. Diffraction gratings work through multiple-slit interference.
Diffraction gratings are used to make very accurate measurements of the wavelength of light. In theory, they function much the same as two slit apertures (recall Activity 4.1 from the 4 th practicals session).
