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.

Repeat the measurements for different angles of incidence to ensure accuracy. 3. Data Analysis In this lab, I determined the refractive index

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. Repeat the measurements for different angles of incidence

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 ( Draw a perpendicular line to the surface at this point
