Object: To determine the wavelength of sodium light by means of Newton’s rings. • Newton's rings is a phenomenon in which an interference pattern is created by the reflection of light between two surfaces; a spherical surface and an adjacent touching flat surface. It is named after Isaac Newton, who investigated the effect in 1666. When viewed with monochromatic light, Newton's rings appear as a series of concentric, alternating bright and dark rings centered at the point of contact between the two surfaces. When viewed with white light, it forms a concentric ring pattern of rainbow colors, because the different wavelengths of light interfere at different thicknesses of the air layer between the surfaces. The pattern is created by placing a very slightly convex curved glass on an optical flat glass. The two pieces of glass make contact only at the center. At other points there is a slight air gap between the two surfaces, increasing with radial distance from the center. • Playlist for physics practicals in hindi. • • Physical Labs • Please subscribe for more videos every month. • YouTube- / @rohitguptaphysics • Facebook- / therohitguptafbpage • Instagram- / the_rohit_gupta_instagm • Twitter- https://twitter.com/RohitGuptaTweet?t... • Copyright Disclaimer under Section 107 of the copyright act 1976, allowance is made for fair use for purposes such as criticism, comment, news reporting, scholarship, and research.
