Reflection

The polarization of transverse waves. Let a rope AB be passed through two parallel vertical slits S1 and S2 placed close to each other. The…

The plane containing the optic axis in which the vibrations occur is known as the plane of vibration. Plane of vibration of a polarized light…

In an unpolarized light, the vibrations in all directions may be supposed to be made up of two mutually perpendicular vibrations. These are represented by…

Two separate wavefronts originating from two coherent sources produce interference. Secondary wavelets originating from dissimilar parts of the similar wavefront constitute diffraction. The vital difference…

Experiment to determine the wavelength of monochromatic light using a plane transmission grating The wavelength of a spectral line can be very accurately determined with…

Determination of Wavelengths of Spectral Lines of White Light: Monochromatic light is now replaced by the given source of white light. The source emits radiations…

An essential application of interference in thin films is the arrangement of Newton’s rings. Newton’s Rings are rings caused by the slim film effect. You…

Sound is propagated in the form of waves. Sound produced in an adjoining room reaches us after bending round the edges of the walls. Similarly,…

Diffraction phenomenon can be classified under two groups (i) Fresnel diffraction and (ii) Fraunhofer diffraction. In the Fresnel diffraction, the source and the screen are…

An arrangement consisting of a large number of equidistant parallel narrow slits of equal width separated by equal opaque portions is known as a diffraction…
