Question

what is the speed of light in oil​

Answer 1

Explanation:

This occurs when the light travels at different speeds through materials with different densities. The speed of light in a vacuum is 299,792,458 m/s, which is represented by the letter c. The equation for speed of light in a materials equals speed of light in a vacuum divided by the index of refraction (v = c/n).

Answer 2

heyy mate...!!!

This depends on the type of oil. Look-up the refractive index for the type of oil you want.

E.g. from the link:

Oil, cedar 1.516

Oil, vegetable 1.47

Oil, oiive 1.46

Oil, turpentine 1.47

Then divide the speed of light in a vacuum (3x10^8 m/s) by the refractive index.

For example, for olive oil the speed is:

3x10^8/1.46 = 2.05x10^8 m/s
