WebJul 5, 2024 · Snell's Law. Snell's law relates the sines of the angles of incidence and transmission to the index of refraction for each material: (3) sin θ 1 sin θ 2 = n 2 n 1. It should be noted that the angles are measured from the normal line at the interface (Figure 1). Figure 1: Refraction at the interface between two materials (Wikipedia) WebThere is a critical incident angle θ1 for which θ2=90° At this critical angle, Snell's law says n1 sin(θcrit) = n2 sin(90) = n2 or sin(θcrit) = n2/n1 The light is no longer really "escaping" the glass. If θ1 gets any larger than this critical value, you cannot solve Snell's law any more for θ2: sin(θ2)>1 is not mathematically possible.

WebLight rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing.
