LAB REPORT
Summary

This report primarily discusses two experiments to study the index of refraction through an
optical or transparent medium. The objectives of the two experiments are to


To study the dependence of the angle of refraction angle on the incidence angle



To study the dependence of the angle of refraction on the angle of incidence
Criticism

Experiment One

When the laser light falls from the air to an optical or a transparent medium, the
refraction index will increase, thus decr...
