Question

Q1 Define refraction of light, Refractive index, Optical density.​

Answer 1

Answer:

1. Refraction of light is the phenomenon of change in the path of light in going from one medium to another.
2. Refractive index is a measure of how much speed of light changes when it enter the medium from air.
