Speed of light in air (which has an index of refraction of 1) is 3 * 10^8 m/s.
So divide the speed of light by the index of refraction of the new medium to obtain the speed of light in that medium.
Hope I helped!!
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
The index of refraction of a substance is inversely proportional to the speed of light in that substance. This means that as the index of refraction of a substance increases, the speed of light in that substance decreases.
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of refraction.
Index Of Refraction
c divided by the index of refraction of the medium = the speed of light in the medium.
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
Index of refraction can be calculated using the formula n = c/v, where n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the medium. Just divide the speed of light in a vacuum by the speed of light in the medium to find the index of refraction for that medium.
Increasing the medium's index of refraction causes the angle of refraction to decrease when light passes from a medium with a lower index of refraction to a medium with a higher index of refraction. This is due to the relationship described by Snell's Law, which governs the change in direction of a light ray as it passes from one medium to another.
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.
Light bends away from the normal (angle of incidence < angle of refraction) and travels at a faster speed in the medium with lower index of refraction.
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.

The index of refraction of a substance is inversely proportional to the speed of light in that substance. This means that as the index of refraction of a substance increases, the speed of light in that substance decreases.
