WebThe refractive index, n, is dimensionless since it's a ratio. It has the formula n = c v, where c is the speed of light in vacuum and v is the speed of light in the medium. Both … WebIt is given by. n 1 sin θ 1 = n 2 sin θ 2. 16.6. 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.
