The absolute refractive indices of water and glass are 1.34 and 1.23, respectively. If the speed of light in glass is 2 10⁸ m/s, find:

(i) Speed of light in vacuum
(ii) Speed of light in water

A) (i) 3 10⁸ m/s, (ii) 2 10⁸ m/s
B) (i) 2 10⁸ m/s, (ii) 3 10⁸ m/s
C) (i) 3 10⁸ m/s, (ii) 1.5 10⁸ m/s
D) (i) 1.5 10⁸ m/s, (ii) 3 10⁸ m/s
