The absolute refractive indices of water glass amd diamond are 1.77, 1.50 and 2.72 respectively, which medium is most optically denser ? Page 45 Chapter - 2.Reflection and Refraction |

Answer» : Diamond Explanation Absolute refractive index is the RATIO of speed of LIGHT in vacuum compared to that of speed of light in medium. where, n represents the absolute refractive index, c - speed of light in vacuum ( generally we take it as 3 * 10^8 m/s), v is the speed of light in the medium. Now, Optically rarer or denser medium is DEFINED upon refractive indices. A medium whose refractive index is more than the other is said to be Optically denser than the other. Given, The absolute refractive indices of water glass and diamond are 1.77, 1.50 and 2.72 RESPECTIVELY. The medium with comparatively more refractive index is diamond, and Hence its most optically denser. |
