determine the refractive index of a transparent liqiud
The value of refractive index is different for each type of plastic.
The value of refractive index is different for each type of plastic.
A transparent medium is sometimes said to have a high optical density (or to be relatively dense) if it has a high refractive index.
The speed varies according to the refractive index of the objects.
It is the extent of the change in the direction of light as it passes from one transparent medium to another.
nothing Anything that is transparent will have a refractive index. Glass is transparent to visible light and has a refractive index with it. Having these combined properties lets you make a lens for visible light out of glass. Now glass is transparent to IR radiation so any glass lens would focus IR radiation.
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)
If it is perfectly transparent, nothing. It can refract and reflect the light. For example, a lens is made of glass which is transparent. The important properties are the refractive index of the material and the angle that light hits the object at.
Refractive Index: 1.4465
Refractive Index: 2.4175-2.4178
Refractive index of vacuum is 1.
