What is the refractive index of kerocine?
The refractive index of kerosene at 20°C is approximately 1.448.
What is refractive index of a lens?
The ratio of the velocity of light in a vacuum to that in a medium is the refractive index of a lens. It is represented by n = c/v, where n = refractive index , v = characteristic speed and c = speed of light 299792 kmsec-1 or 1 Planck speed.
What happens to the speed of light when it passes through water?
It slows from c to c/n where n is the refractive index of water
What is the property of a material that indicates how much it reduces the speed of light?
I think the property referred to on the question is the refractive index. Refractive index (n) is defined as the ratio of the speed of light in a vacuum (c) to the speed of light in the given material (v).n = c/vSo for glass, with a refractive index of 1.5, the speed of light in the material would be 200,000,000 m/s compared to speed of light in a vacuum of 300,000,000 m/s.
Is this true or false that light moves slower through water than through air?
Yes it is true. If c is the speed of light in air then in water it will be 3/4 of c Hence refractive index of water = speed of light in air/speed of light in water So refractive index = 4/3 = 1.333
What is the refractive index of kerocine?
The refractive index of kerosene at 20°C is approximately 1.448.

What is the refractive index of a plastic semi circle?
The value of refractive index is different for each type of plastic.
Differences between relative refractive index and absoulate refractive index?
Refractive Index(i) Refractive index of a medium is that characteristic which decides speed of light in it.(ii) It is a scalar, unit less and dimensionless quantity.(iii) Absolute refractive index :When light travels from vacuum to any transparent medium then refractive index of medium w.r.t. vacuum is called it's absolute refractive index i.e. vacuumµmedium = c/vAbsolute refractive indices for glass, water and diamond are respectively µg = 3/2 = 1.5, µw = 4/3 = 1.33 and µD = 12/5 = 2.4(iv) Relative refractive index :When light travels from medium (1) to medium (2) then refractive index of medium (2) w.r.t. medium (1) is called it's relative refractive index i.e. 1µ2 = µ2/µ1 = v1/v2 (where v1 and v2 are the speed of light in medium 1 and 2 respectively).(v) When we say refractive index we mean absolute refractive index.(vi) The minimum value of absolute refractive index is 1. For air it is very near to 1. ( 1.003)
What is the speed of light through the liquid whose refractive index you have determined?
If the refractive index is k then the speed of light is c/k metres per second where c is the speed of light in vacuum (approx 299,792,458 m/s).
What is the speed of light in a glass fiber optic cable with a refractive index of 1.52?
In any medium whose refractive index is 1.52, the speed of light is c/1.52 = 0.658 c =197,231,880 meters per second (rounded)
What happens to the speed of light when it passes through water?
It slows from c to c/n where n is the refractive index of water
Does Light Travel More slowly in a Medium?
Light travels at its maximum velocity c in a vacuum. In a medium with a certain refractive index, it is slowed down and travels with velocity c/index
What is the property of a material that indicates how much it reduces the speed of light?
I think the property referred to on the question is the refractive index. Refractive index (n) is defined as the ratio of the speed of light in a vacuum (c) to the speed of light in the given material (v).n = c/vSo for glass, with a refractive index of 1.5, the speed of light in the material would be 200,000,000 m/s compared to speed of light in a vacuum of 300,000,000 m/s.
When light travels from air to glass its speed is what?
The ratio between the speed of light in vacuum, c, and the speed at which light travels in a material, v, is called the refractive index of the material.The refractive index of air for visible light is 1.000293, so the speed of light in air is c / 1.000293 ≈ 299,705,000 m/s. The refractive index of glass, depending on the type of glass, for visible light is around 1.5, so the light in glass travels at c / 1.5 ≈ 200,000,000 m/s.
