Fringe width is a term used for the width of the first maxima in diffraction. It can also be found by calculation by dividing the wavelength of the light input multiplied by the distance between the slits and the screen by the space between the slits.

What is the angular fringe width in newtons rings?

The angular fringe width in Newton's rings is given by the equation δθ = λ / R, where δθ is the angular fringe width, λ is the wavelength of light, and R is the radius of curvature of the lens or mirror producing the rings. It represents the distance between adjacent bright or dark fringes in the pattern.


What is the formula for fringe width?

Fringe width (for dark and bright bands): D * wavelength / d where, D = distance between screen and coherent sources (metres), wavelength = wavelength of light used is experiment (nanometres), d = distance between the 2 coherent sources (millimetres).


What is the fringe width of NEWTON RING?

The fringe width of Newton rings is the distance between two consecutive bright or dark fringes observed when a plano-convex lens is placed on a flat glass plate. It is given by the formula [ w = \lambda \cdot R / (D - R) ], where ( \lambda ) is the wavelength of light, ( R ) is the radius of curvature of the lens, and ( D ) is the diameter of the bright ring.
