Light rays are incident on devices which may cause either reflection or refraction both. The natures of the incident light and the devices are described in column I. Some possible results of this on the rays are given in column II.
Column I | Column II |
(i) A ray of white light is incident on one face of an equilateral prism | [A] Divergent beam |
(ii) A ray of white light is incident at an angle on a thick glass sheet. | [B] Total internal reflection |
(iii) A ray of white light passes from optically denser medium to rarer medium. | [C] Lateral shift |
(iv) A parallel beam of monochromatic light passes symmetrically through a glass lens. | [D] Dispersion |
