  • Refraction of Light

    Definition and description of refraction of light

    Optical density of a medium explained

    3 cases of Refraction discussed:

         CASE 1:  Refraction of Light from opticallly less dense to optically more dense medium   

         CASE 2:  Refraction of Light from opticallly more dense to optically less dense medium   

         CASE 3:  Light entering a medium along the normal

    Examples of Refraction in everyday life discussed and explained:

        Example 1- Bending of a pencil image when placed in a beaker of water

        Example 2: Swimming pool appearing shallower due to refraction of light

    Terms in Refraction explained:

        - Incident Ray

        - Refracted Ray

        - Angle of incidence

        - Angle of Refraction

        - Bending of refracted ray towards the normal

        - Bending of refracted ray away from the normal
