When the incident angle equals the critical angle ( θ 1 = θ c ), the angle of refraction is 90° ( θ 2 = 90°). Noting that sin 90° = 1, Snell’s law in this case becomes. n 1 sin θ 1 = n 2. The critical angle, θ c, for a given combination of materials is thus.
WebMar 4, 2024 · Snell's law, or the law of refraction, describes the relationship between the angles of incidence θ₁ and refraction θ₂ and the refractive indices ( n ₁, n ₂) of two media: n ₁sin (θ₁) = n ₂sin (θ₂). The law of refraction allows us to predict the amount of bend when light travels from one medium to another. Does Snell's law apply to all waves?
