To measure the absolute refractive index of a glass plate using Snell's law.

Mark a point on one edge where the light ray will enter. Draw a perpendicular line to the surface at this point. Draw an incident ray at an angle (e.g., 30∘30 raised to the composed with power 45∘45 raised to the composed with power ) to the perpendicular. To measure the absolute refractive index of a
