Question

The rays of light are entering from glass into glycerine. If the absolute refractive indices of glass and glycerine are 1.5 and 1.47 respectively, find the refracting index of glycerine relative to glass.Solve the given problem (Ans :0.98)

Answer 1

Given conditions ⇒

Absolute Refractive Index of Glass = 1.5

Absolute Refractive Index of Glycerine = 1.57

∵ Refractive Index of glycerine w.r.t to glass = Absolute Refractive Index of glycerine/Abso. Refrac. Index of glass.

= 1.47/1.5

= 0.98

Hence, refracting index of glycerine relative to glass is 0.98.

Hope it helps.
