Polarization by Reflection: The simplest method of producing plane polarized light is by reflection. Malus discovered that when a beam of ordinary light is reflected from…

Sir David Brewster conducted a series of experiments with different reflectors and found a simple relation between the angle of polarization and the refractive index…

The phenomenon of polarization by reflection is used in the construction of pile of plates. It consists of a number of glass plates placed one…

The phenomena of reflection, refraction, interference, diffraction are common to both transverse waves and longitudinal waves. But the transverse nature of light waves is demonstrated…

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…

A device which produces plane polarized light is called a polarizer. A device which is used to examine, whether light is plane polarized or not…

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…
