Diffraction Grating: an Overview on Diffraction Grating
This concept of diffraction grating has its principles based on Physics. To diffract is mainly an aspect of light passing through sharp edges or going through narrow slits. The rays are deflected and produce fringes of both light and dark bands.Diffraction gratingis based on the same principle where light reflections on such items like CDs, DVDs and blue-ray discs produces an array of colorful light.
It occurs due to the separation of light into different rays of light with varying wavelengths. These wavelengths are combined to form different beams of light. This concept has been used in many ways to give a beautiful impression of objects and places. For instance, in nightclubs, various colors of light are used. This makes the nightclub more attractive. In planetariums,diffraction gratingis also used to produce colorful lighted environment. The concept is applied on a single laser, which creates many other light beams that resemble the stars of the sky or sometimes a portion of moving neon light in the atmosphere.
