Question

1] Different media have different refractive index why? ​

Answer 1

Answer:

this is because speed of light in different media is different

Answer 2

Different media have different refractive indices because:

• Refractive index of a medium is defined as the ratio of the speed of light in a vacuum to the speed of light in that medium.
• Different media interact differently with light.
• So, the speed of light is different in different media.
• Hence, the refractive index of different media is different.
