Phenomenon of double refraction was explained by Huygens’ for which he extended his principle of secondary wavelets and made the following assumptions. • Light passing through a calcite crystal is split into two rays.

When a ray of light enters the gemstone, the atomic structure allows only those rays vibrating in two specific directions to continue. endstream endobj 449 0 obj <>stream Therefore, the phenomenon of splitting of light into two rays is known as. • Double refraction is an optical property in which a single ray of unpolarised light when passes through a uniaxial crystal gets split into two refracted rays, each propagating in a different direction. %PDF-1.5 %���� endstream endobj 450 0 obj <>stream These two wavelets spread out into the crystal. ]^�~�������ќG96k9/nv���y����h� �� |;de�"���!�������&�C�7>���υ�.���v Z�!��9��Ue�8�Ygd#��/���0j��M�=2 �XK�8��>�(�\!����CJ��J���Jr[b�c>��|k+��|����o_ B��if��A�����_f|GE� ��e����O�J�����N%�=�oW�h�F��@:��a��k��2���㠕o��z�q�V=i�[a�j'�l�y�$����0 \�� endstream endobj 439 0 obj <>stream • When a light wave strikes the surface of a doubly refracting crystal, each point of the crystal becomes the origin of two secondary wavelets, named as ordinary ray and extraordinary ray. �0 Ы̮ ��4m�P In contrast, we propose to optically resolve this ambi-guity by exploiting the fact … Popular topic for study.
