A ray of light enters into medium B from medium A as shown in the given figure :
(a) Which one of these two media is optically denser than the other medium ? Justify your answer.
(b) If the speed of light in medium A is VA and in medium B is VB, then what is the refractive index of medium B with respect to medium A ?
Solution
(a) Medium A is optically denser than B because light ray is going away
from the normal NN’.
(b) nBA = 𝑉𝐴
𝑉
𝐵
