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

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.

You can find digital versions of the lab manual and ready-made answers on platforms like Gitem or Infourok . Observe the ray as it passes through the glass
