What is refractive index of water?

Answers

Answered by SᴘᴀʀᴋʟɪɴɢCᴀɴᴅʏ

the refractive index or index of refraction of a material is a dimensionless number that describes how fast light travels through the material. It is defined as

{\displaystyle n={\frac {c}{v}},}

where c is the speed of light in vacuum and vis the phase velocity of light in the medium. For example, the refractive index of water is 1.333, meaning that light travels 1.333 times as fast in vacuum as in water. Increasing refractive index corresponds to decreasing speed of light in the material.

HOPE IT HELPS UH!!☺️
