What is the speed of light in oil?

Answer 1

Einstein says that the speed of light is the same to all observers. This raises some interesting problems and his theories of relativity set out to solve them. But that aside, the speed of light is the same in olive oil and a diamond as it is anywhere else.

Answer 2

The speed of light in oil is slower than in a vacuum due to the increased refractive index of oil compared to air. The exact speed will depend on the specific type of oil and its properties.

Answer 3

Light refracts when it passes from rarer medium to denser medium & vice versa.

As air is optically rarer & oil is optically denser, light will be refracted.

Answer 4

It changes when the light enters the oil, and again when the light

leaves the oil, but not while the light is in the oil.

Answer 5

It will get bent.The bending will depend on what the medium is from which it enters the oil.

Answer 6

The speed of light doesn't change.
