Absolute refractive indices of glass and water are `3//2` and `4//3`.

1.	Absolute refractive indices of glass and water are `3//2` and `4//3`. The ratio of velocity of light in glass and water will beA. `4 : 3`B. `9 : 8`C. `8 : 9`D. `3 : 4`
Answer» Correct Answer - C (c ) As, `µ=(c)/(v)rArrvprop1/µ` `therefore` `v_(1)/v_(2)=µ_(1)/µ_(2)` `rArr` Ratio of velocities of light `v_(g)/v_(w)=µ_(w)/µ_(g)=(4//3)/(3//2)=8/9`
