The refractive index depends on the wavelength of the radiation.
Traditionally the sodium line NaD20 (589,3 nm) is used for measurements (20 is the temperature on the Celsius scale).
The refractive index of vinegar typically ranges from 1.334 to 1.345, depending on factors such as the concentration of acetic acid and any impurities present.
Diamond, when measured in liquid form. Liquid diamond has a refractive index of approximately 2.417, which is higher than any other liquid.
When light passes from one substance to another, and both have the same refractive index, then there will be no refraction - or change of direction - at the border. It is as if there were only one substance.
No, there is no direct relationship between the boiling point and refractive index of a substance. Boiling point is a physical property related to the temperature at which a substance changes from a liquid to a gas, whereas refractive index is a measure of how light propagates through a material.
1Ideally speaking, the ratio of the sines of the angles of incidence and refraction will be the same if the medium is the same. So the refractive index will be 1.However, refractive index is, again, a relative value. If we say that the refractive index of glass is 1.5, it implies that the refractive index of glass, with respect to air is 1.5. So the value might change based on the media involved in refraction.It can also be safely concluded, without much Physics, that any multiplicative quantity for the standard element will be 1. (ex: speed of sound is Mach 1)
Yes. Normally the refractive index is slightly different for different wavelengths.
The speed of light in any medium isspeed of light in vacuum/refractive index of that medium.

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)
The prism is an optical device which offers different refractive index for different colours. If we take the case of white light which consists of "VIBGYOR". The red light will have less refractive index when compared to Violet or Blue colurs. The refractive index depends on the wavelength of the incident wave. If the wavelength is more , refactive index is less and vice versa. Uma
Diamond, when measured in liquid form. Liquid diamond has a refractive index of approximately 2.417, which is higher than any other liquid.
The refractive index of any substance is(speed of light in vacuum)/(speed of light in that substance) .The number is greater than ' 1 ' in any material medium.

Everything a lens does is the result of the change of refractive index at its surface.If the lens is surrounded by a medium with the same refractive index as the glass,then there is no refraction (bending) of light at the glass surface, and the lens is nolonger a lens. If you could find such a liquid, you might not even be able to see thatthere's a lens down there in it.
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)
