Answer:
The refractive index of a material is a measure of how much a material bends light as it passes through it. The refractive index of a material is defined as the ratio of the speed of light in a vacuum to the speed of light in the material. A refractive index of 2.42 for diamond means that light travels through diamond at about 42% slower than it does in a vacuum. This high refractive index is due to the high density and strong chemical bonds of the carbon atoms in diamond. This high refractive index gives diamond its characteristic brilliance and fire, and makes it
