Question

refractive index???​

Answer 1

Answer:

1.This is a measure of how much light slows down when it goes though a particular medium.

2.symbol n

3. n ( vacuum) =1

n( medium) = C( speed of light in vacuum) / V ( speed of light in medium

Refractive Index

The extent to which light bends when moving from one medium to another is called refractive index. This depends on the ratio of the speeds in the two media. The greater the ratio, more the bending. It is also the ratio of the sine of the angle of incidence and the sine of the angle of refraction, which is a constant for any given pair of media. It is denoted by:

n = sin∠i/sin∠r = speed of light in medium 1/ speed of light in medium 2.
