Reflection of Light by Mirror

Experiment: Reflection of Light by Mirror Task: Reflection of light by mirror. Required accessories: A plane mirror and a torch-light. Procedure: Keep the minor on......

Define and Describe on Polaroids

A Polaroid is a material which polarizes light. The phenomenon of selective absorption is made use of in the construction of polariods. There are different......

Explain Uses of Polaroid

Uses of Polaroid Polaroids are used in the laboratory to produce and analyze plane polarized light. Polaroids are widely used as polarizing sun glasses. They......

Define and Describe on Double Refraction

Bartholinus discovered that when a ray of unpolarised light is incident on a calcite crystal, two refracted rays are produced. This phenomenon is called double......

Describe on Nicol Prism

Nicol prism was designed by William Nicol. One of the most common forms of the Nicol prism is made by taking a calcite crystal whose......

Explain Types of Crystals

Crystals like calcite, quartz, ice and tourmaline having only one optic axis are called uniaxial crystals. Crystals like mica, topaz, selenite and aragonite having two......

Explain Polarization by Reflection

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......

Describe Brewster’s Law

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......

Explain on Pile of Plates

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......

Define Polarization

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......

Explain Polarization of Transverse Waves

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

Define Plane of Vibration and Plane of Polarization

The plane containing the optic axis in which the vibrations occur is known as plane of vibration. The plane which is at right angles to......
