refractive index is the ratio of speed of light in vaccum to the speed of light in actual substance
Explanation :- Actually light moves in a straight line with a speed 3X108 in vacuum only , in other substances the speed of light is decreased due to the bombardment of molecules of the substance. Refractive index also gives us the information about the amount of bending the light suffers when it enters from one medium to other.
Yes. Normally the refractive index is slightly different for different wavelengths.
The refractive index of petrol (gasoline) typically ranges from about 1.4 to 1.5. This value can vary slightly depending on the specific composition of the petrol, including factors like temperature and the presence of additives. The refractive index is a measure of how much light slows down and bends as it passes through the substance compared to air.
