Question

what is the unit of refractive index of any light medium?​

Answer 1

Explanation:

refractive index have no si units, since from the definition refractive index is the ratio of velocity of light in a material divided with velocity of light in vacuum. this is what is meant by "integral".

Answer 2

➤ Answer :-

⟶ Refractive index has no units.

• Refractive index have no si units, since from the definition refractive index is the ratio of velocity of light in a material divided with velocity of light in vacuum. this is what is meant by "integral".
• As it is a ratio between velocity of light in material vs velocity of light in vacuum, both unit for the velosity was cancelled out and the only thing left is the number which indicates the ratio.
• And that ratio is the refractive index. But there are a lot of expression can described the refractive index.
• For example in brix percent, the expression is depend on the application.
