State the laws of refraction of light. Explain the term 'absolute refractive index of a medium' and write an expression to relate it with the speed of light in vacuum.

State the laws of refraction of light. If the speed of light in vacuum is 3 xx10^8 m/s, find the absolute refractive index of a medium in which light travels with a speed of 1.4 xx 10^8 m/s.

State the law of refraction of light that defines the refractive index of a medium with respect to the other. Express it mathematically. How is refractive index of any medium A with respect to a medium B relate to the speed of propagation of light in two media A and B ? State the name of this constant when one medium is vacuum or air ? The refractive indices of glass and water with respect to vacuum are (3)/(2) and (4)/(3) respectively. If the speed of light in glass is 2 xx 10^(8) ms^(-1) , find the speed of light in (i) vacuum, (ii) water.

(a) State the laws of refraction of light. Explain the term absolute refractive index of a medium and write an expression to relate it with the speed of light in vaccum. (b) The absolute refractive indices of two media 'A' and 'B' are 2.0 and 1.5 respectively. If the speed of light in medium 'B' is 2 xx 10^(8) ms^(-1) , calculate the speed of light in (i) vaccum (ii) medium 'A'.
