Repeat the measurements for different angles of incidence to ensure accuracy. 3. Data Analysis
) of a medium shows how many times the speed of light in a vacuum ( ) is greater than its speed in the medium (
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.
