Refractive index of glass with respect to medium is `(4)/(3)`. If `v_(m) - v_(g) = 6.25 xx 10^(7)` m/s., then velocity of light in medium is

The refractive index of glass W.t.r. a medium is 4/3 . If v_m - vg = 6.25 xx 10^(7) m/s. then the velocity of light in the medium will be

The refractive index of glass w.t.r. a medium is 4/3 . If v_m - m_E = 6.25 xx 10^(7) m/s. then the velocity oflight in the medim will be

If the refractive index of a medium is 1.7, the velocity of light in that medium is

The refractive index denser medium with respect to rarer medium is 1.125 The difference between the velocities of light in the two media is 0.25times10^(8)m/s .Find the velocities of light in the two media and their refractive indices c=3times10^(8)m/s

The velocity of light in glass whose refractive index with respect to air is 1.5 is 2 xx 10^8 m//s . In a certain liquid the velocity of light is found to be 2.5 xx 10^8 m//s . The refractive index of the liquid with respect to air is :

The refractive index of a medium is 1.7 the velocity of light in this medium is
