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. Potential errors in the experiment may arise from

Repeat the measurements for different angles of incidence to ensure accuracy. 3. Data Analysis Data Analysis )

). According to the , the ratio of the sine of the angle of incidence ( ) to the sine of the angle of refraction ( ) is constant for two given media:

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

Calculate the refractive index for each trial using the formula
