Question

define relative refractive index and write its formula​

Answer 1

Answer:

Explanation:

When we measure speed of light in two different media, relative refractive index of medium 2 with respect to medium 1 is defined as the ratio of speed of light in medium 1 to speed of light in medium 2.

Answer 2

Answer: we can find the relative refractive index 1n2 by dividing the speed of light in material 1 (c1) by the speed of light in material 2 (c2) OR by dividing the refractive index of material 2 (n2) by the refractive index of material 1 (n1)

Explanation:

relative refractive index of medium 2 with respect to medium 1 is defined as the ratio of speed of light in medium 1 to speed of light in medium 2. n21= speed of light in 1st medium / speed of light in second medium.
