What is Diffraction? Diffraction is when waves like light or sound spread out as they move around an object or through a slit. When light passes through each of the…

Diffraction from a single slit gives a characteristic pattern. It also complicates the pattern from Young’s experiment. Here we use phasor addition to derive the intensity as a function of…

What is Diffraction of Light? Diffraction is the slight bending of light as it passes around the edge of an object. The amount of bending depends on the relative size…

What is Newton’s Ring? When a plano-convex lens with its convex surface is placed on a plane glass sheet, an air film of gradually increasing thickness outward is formed between…

In everyday life, the interference of light most commonly gives rise to easily observable effects when light impinges on a thin film of some transparent material. For instance, the brilliant…

Interference of Light: Definition:  When two light waves from different coherent sources meet together, then the distribution of energy due    to one wave is disturbed by the other. This modification in…

What happens when two waves meet while they travel through the same medium? What effect will the meeting of the waves have upon the appearance of the medium? Will the…

Wave Optics : To explain some phenomena, such as interference and diffraction of light, it is necessary to go beyond geometrical optics. Huygens’ Principle Huygens considered light to be a…

A particle in a 1-dimensional box is a fundamental quantum mechanical approximation describing the translational motion of a single particle confined inside an infinitely deep well from which itcannot escape.…
