Explanation:
Detailed explanation-1: -If the speed of light in air is 3 x 108 m/s and the refractive index of water is 1.33, find the speed of light in water. (Ans. 2.25 x 108 m/s)
Detailed explanation-2: -Refractive index () = 1.33; Speed of light in air(c) = 3 x 108; Speed of light in water =? ⇒ v= 2.25 × 108m/s.
