Answer 2

After filling the blanks the correct passage will be -

The extent of change in the dire direction of light ray is different for different media and  depends upon the refractive index of the medium. The value of refractive index depends on the Velocity of the  light in the medium.

The refractive index (152) of second medium with respect to the first is given by  ratio of the magnitude of velocity of light in first medium (V1) to that in second  medium(V2).

Velocity of light in a medium depends on the frequency of light and thus different  colours travel with different velocity in a medium. Therefore, refractive index of a medium is  different for different colours the product altionicom​
