Light travels with a velocity 1.8 x 10^8 m/s in medium 1 and enters into second medium. Its velocity becomes 0.95 x 10^8 m/s in second medium. What is the refractive index of second medium with respect to first medium?

Explanation:
Velocity of light in a first medium = V1 = 1.5 x 108 m/s Velocity of light in second medium = V2 = 0.75 x 108 m/s Refractive index of second medium = 2n1 = ? 2n1 = 1 / 2 2n1 = 1.5 x 108 / 0.75 x 108 = 2 Hence, the refractive index of second medium with respect to first medium is 2.Read more on Sarthaks.com - https://www.sarthaks.com/355562/light-travels-with-velocity-10-in-medium-on-entering-second-medium-its-velocity-becomes-10
