Answer 2

Refractive Index:

Explanation:

Refractive index definition:

• Refractive index, also called index of refraction, measure of the bending of a ray of sunshine when passing from one medium into another. ratio is additionally adequate to the rate of sunshine c of a given wavelength in empty space divided by its velocity v in an exceedingly substance, or n = c/v.

• The ratio is of two types: Absolute ratio. Relative ratio.

        Some ratio are as follows as:

• Refractive index of glass is 1.5.

• Refractive index of water is 1.33.

• Refractive index of ruby is 1.77.

• Refractive index of Diamond is 2.417

• Refractive index of Strontium titanate is 2.41

• Refractive index of Tantalum pentoxide is 2.15
