Q1
A light ray travels from medium 1 (refractive index n₁) to medium 2 (refractive index n₂). According to Snell's law, which equation correctly relates the angles of incidence (θ₁) and refraction (θ₂)?
Q2
When light undergoes total internal reflection at the interface between a denser medium and air, what is the critical angle θc related to by?
