By measuring these angles, we can calculate the optical density of the glass. 2. Experimental Procedure

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

A glass plate with parallel edges (or a prism), a piece of cardboard, pins (or a laser pointer), a ruler, a protractor, and a pencil. 1. Theoretical Background The refractive index ( By measuring these angles, we can calculate the

n=sinαsinβn equals the fraction with numerator sine alpha and denominator sine beta end-fraction

Below is a structured template (essay/report) you can use for this work: A glass plate with parallel edges (or a

Connect the entry and exit points to visualize the refracted ray inside the glass. Use a protractor to measure the angle of incidence ( ) and the angle of refraction (

In this lab, I determined the refractive index of glass by measuring the angles of light propagation at the boundary of two media. The results confirm that as light enters a more optically dense medium (glass) from a less dense one (air), the ray bends toward the normal. Potential errors in the experiment may arise from the thickness of the pencil lines or slight misalignments of the pins/laser. Use a protractor to measure the angle of

Observe the ray as it passes through the glass. Mark the exit point on the opposite side of the plate.
