Refractive indices of ice and flint glass are 1.309 and 1.655 respectively. If the speed of light in ice is `1.292*10 ^ (8)m/s`, determine the same in flint glass.

Fill in the blank spaces with appropriate answers: The refractive indices of water and glass are (4/3) and (3/2) respectively. If the speed of light in water is 2.25 xx 10^8 m//s) then the speed of light in glass is _______ m/sec.
