ctets15p2 q62
0. Medium A is optically denser than Medium B. Which one of the following statements is true?
- Option : D
- Explanation : (D) The speed of light is less in the optically dense medium because these are more atoms in the dense medium to obstruct the path of the light. Light is an electromagnetic wave and its speed depends upon the optical density of the medium. As the density of the medium increases, the speed of the light wave decreases.
