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. Web19 jan. 2024 · The value of the index of refraction mostly comes out to be equal to or greater than 1, as the speed of light in a vacuum is always higher than the speed of light in any other medium. However, in some cases, refractive indices lower than unity (less than 1) do exist. Some metamaterials even have negative refractive indices ( Source ).

WebRefraction and Reﬂection 1 Refraction When we discussed polarization, we saw that when light enters a medium with a diﬀerent index of refraction, the frequency stays the same but the wavelength changes. Using that the speed of light is v = c n we deduced that λ1n1=λ2n2, so that as the index of refraction goes up, the wave-length goes down.
