Vedclass · Answer

(D) In a doubly refracting (birefringent) crystal,the incident unpolarised light splits into two plane-polarised rays.$1$. The ordinary ray ($O$-ray) obeys the standard laws of refraction and its vibrations are perpendicular to the principal section (plane of incidence).$2$. The extraordinary ray ($E$-ray) does not obey the standard laws of refraction and its vibrations occur within the principal section (plane of incidence).Therefore,the $E$-ray is polarised in the plane of incidence,and the $O$-ray is polarised perpendicular to the plane of incidence.Thus,the correct option is $(D)$.

When light is incident on a doubly refracting crystal,two refracted rays-ordinary ray ($O$-ray) and extraordinary ray ($E$-ray) are produced. Then:

Two polaroids have their polarizing directions parallel so that the intensity of the transmitted light is maximum. The angle through which either polaroid must be turned so that the intensity of the transmitted light is dropped to one-half of the previous transmitted intensity is $.....^\circ$.

Two polaroids $A$ and $B$ are placed perpendicularly in the path of a beam of unpolarized light. In between these two,a third polaroid $C$ is placed at an angle of $30^o$ with that of $A$. The percentage of intensity of incident unpolarized light that emerges from $B$ is ........$\%$.

Two polarizers are placed such that the angle between their transmission axes is $60^o$. If unpolarised light of intensity $I_0$ is incident on the first polarizer,then the transmitted intensity from the second polarizer will be
