The subject of laboratory work No. 3 in the 11th-grade physics curriculum by S.A. Tikhomirova and B.M. Yavorsky is .
Place the glass plate on a sheet of paper and trace its outline.
Below is a structured template (essay/report) you can use for this work:
n=sinαsinβn equals the fraction with numerator sine alpha and denominator sine beta end-fraction
). 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:
To measure the absolute refractive index of a glass plate using Snell's law.
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.
