Problem
State whether each statement given below is True or False. In each case give a brief justification based on the relation between refractive index, speed of light and optical density.
(a) Light travels faster in crown glass than in water.
(b) A medium of higher refractive index is always optically denser than a medium of lower refractive index.
(c) If the refractive index of medium A with respect to medium B is less than 1, then light will bend toward the normal when it enters medium A from medium B.
(d) The product of refractive index and speed of light in any medium is a constant equal to 3.00×108m s−1.
