Reflection

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…

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…

A Polaroid is a material which polarizes light. It consists of microcrystals of herapathite. Each crystal is a doubly refracting medium, which absorbs the ordinary…

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…

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…

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…

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…
