### device | optical device:

Diffraction grating
* act like a prism and spread light out into a spectrum or a rainbow.
* are optical devices
  - used in many analytical chemistry tools , such as a spectrometer
+ Diffraction, Uses of diffraction: Physics
  * Diffraction can be used to separate different wavelengths of light using a diffraction grating. A diffraction grating can be a series of closely-spaced slits or a mirror with a series of small grooves. Diffraction gratings work because different wavelengths of light will constructively interfere at different angles. Diffraction gratings are used in many analytical chemistry tools, such as a spectrometer.
