Question

Speed of light in water is 2.25 X 108 m/s and in glass is 2 X 108 m/s.
i) Find refractive index in each case.
ii) Which of the two is optically denser?

Answer 1

Answer:

Glass is more denser than water

Explanation:

hope the answer will help you

Answer 2

Answer:

refractive index in water = 1.33

and refractive index in glass is = 1.5

glass is optically more denser
