Question

paraffin oil has greater refractive index than water what does it mean answer briefly in two different ways ​

Answer 1

Answer:

Refractive index of paraffin oil is greater than water.

1. This means light rays travel in a greater speed in water than in paraffin oil. Since [μ =C/V] where C = velocity of light in vacuum and V = velocity of light in the given medium.
2. Again we can say that refractive index of parraffin oil with respect to water is greater than 1.
