PPL MCQ : MCQ on Polarisation - YB Study

# MCQ on Polarisation | PPL MCQ

The phenomenon of polarisation proves that light consists of  transverse waves. It can be demonstrated by using two tourmaline crystals, nicol prism or polaroids. A light wave in which all the vibrations of the electric vector E occur in a single direction, perpendicular to the direction of propagation is said to be a linearly polarised or a plane polarised light wave. Plane of vibration of plane polarised light is perpendicular to the plane of polarisation.

Types of polarised light

(i) unpolarised light

(ii) plane polarised light

(ii) partially polarised light
