Question

medium refractive index

air. 1.0003
water. 1.33
diamond. 2.42
ice. 1.31
kerosene. 1.44
crown glass 1.52
1) in which medium velocity of light is maximum??
2) in which medium velocity of light is minimum??
3) name the substance which has highest optical density??
4) what happened to light when it travels from crown glass to water??
5) name two media in which velocity of light is nearly same​

Answer 1

A ray of light in passing from a transparent medium 1 to another transparent medium 2 slows down. In this case, state whether the refractive index of medium 2 is  the refractive index of medium 1nt at an interface at an angle 60o is refracted into another medium at an angle 30o. If its speed in the first medium is C, then its speed in the second medium
