) of a medium shows how many times the speed of light in a vacuum ( ) is greater than its speed in the medium (

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 . ) of a medium shows how many times

Calculate the refractive index for each trial using the formula

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

n=sinαsinβn equals the fraction with numerator sine alpha and denominator sine beta end-fraction ) of a medium shows how many times

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