NEWTON’S RINGS APPARATUS

NEWTON’S RINGS APPARATUS

MAKE DINESH SCIENTIFIC MODEL DS-606

PRODUCT DESCRIPTION
In this apparatus, light from a sodium lamp falls on the glass plate, inclined at 45 degree to the horizontal, get reflected, and then falls normally on the convex lens placed over the glass plate.
Apparatus: A nearly monochromatic source of light (source of sodium light), a plano-convex lens C, an optically plane glass plate P, an optically flat glass plate G in- clined at an angle of 45◦, a travelling microscope with measuring scale and a spherometer.

FEATURES:
• Low on maintenance
• Smooth functioning
• Ease of usage
To determine the wavelength of sodium light and to find the radius of curvature of planoconvex lens using newton’s rings experiment. The complete setup should include.
