CBSE - X - Physics
Light enters from air to medium X.Its speed in medium Z becomes 1.5X10 raise to the power 8 m/S.Speed of light in air is 3X10 raise to the power 8 m/s.Find the refractive index of medium X?
Refractive index is the ratio of speed of light in air/vacuum to that in a medium.
Therefore, the refractive index of the medium is
