1.	The refractive index of glass is 1.5 and that of water is 1.3, the speed of light in water is 2.25 × 10^8 m/s.

Answer» Correct OPTION is (C) 1.95 × 10^8 m/s Easiest explanation: \( \FRAC {v_g}{v_w} = \frac {\mu_w}{\mu_g}\) Vg = \((\frac {\mu_w}{\mu_g})\) × VW \(\frac {v_g}{v_w} = ( \frac {1.3}{1.5} ) \) × 2.25 × 10^8 \(\frac {v_g}{v_w}\) = 1.95 × 10^8 m/s.
