Question

given below are refractive index of you media identify media in which speed of light will highest and lowest respectively

MEDIUM REFRACTIVE INDEX
DIAMOND 2.42
GLASS 1.5
WATER 1.3
KEROSENE OIL 1.4​

Answer 1

Answer:

the order for highest speed is

water(highest speed)

glass

kerosene oil

diamond(lowest speed)

Explanation:

the more the refractive index the less is its speed as refractive index is ratio of speed of light in vaccum and speed of light in that medium.if speed of medium is more than refractive index will be less.
