Rare median and denser median???? |
|
Answer» Rarer medium:A medium in which the speed of light is more is known as Optically Rarer medium . Air is optically rarer medium as compared to glass and water.Denser medium:A medium in which speed of light is less is known as optically denser medium, glass is optically denser medium as compared to air.The refractive index of a medium gives an indication of density of that meium and also the light bending ability of that medium.For example: Refractive index of glass is greater than the refractive index of water . Hence light bends more in glass than in water.If Refractive index is more bending of light is more and speed of light will be less. Rarer r those which have less molecular composition.and denser r just opposite to it |
