Abstract | A simple method for determination of the refractive index of glass is described.
The glass sample is assembled from window glass plates of dimensions 6 x 35 x 100
mm. A ruler, sheet of paper, pencil and some pins are needed for a
measure of the refractive index. A derivation of the formula for the refractive index is
based on Snell’s law and geometrical picture of the light beam in the sample. |
