ICSE Class 10 Answered

does refractive index also depends upon the temperature of the medium?

answered-by-expert Expert Answer
As per definition, refractive index of a medium is the ratio of speed of light in vaccum to that of in that medium itself. Refractive index is always a relative quantity. It depends on the electrical primitivity, magnetic permeability, molecular polarizability. Besides these factors, it also depend upon size of molecules of the material , configuration or average distance between the successive atoms can be change with variation of temperature so in this way refractive index has a kind of indirect dependence on temperature.

(a) Choose the correct statement with respect to Refraction of light [1] 1. The colour always changes when light enters from one optical medium to another. 2. Absorption of light when it strikes the surface of a medium is refraction. 3. Speed of light changes when it enters from one optical medium to another of different optical density. 4. Speed of light does not change when it enters from one optical medium to another of different optical density.
