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 (
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.
) of a medium shows how many times the speed of light in a vacuum ( ) is greater than its speed in the medium (
). 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:
The subject of laboratory work No. 3 in the 11th-grade physics curriculum by S.A. Tikhomirova and B.M. Yavorsky is .
Observe the ray as it passes through the glass. Mark the exit point on the opposite side of the plate.
