(a) Observe the given ray diagram and compare :
(i) the speed of light in medium A and the speed of light in medium B.
(ii) the optical densities of medium B and medium C.
(b) Draw a ray diagram for refraction where the optical density of medium 'A' becomes equal to the optical density of medium 'C' and optical density of medium 'B' is greater than the optical density of medium 'A' and medium 'C'.
Solution
(a) (i) Speed of light in medium A > Speed of light in medium B.
(ii) Media B and C both have same optical density.
(b)
