Index of refraction and Snell's law
n = c/v · n1 sin θ1 = n2 sin θ2
n index of refraction, v speed in the medium, θ angle from the normal
Watch forInto higher n, light slows and bends toward the normal.
n = c/v · n1 sin θ1 = n2 sin θ2
n index of refraction, v speed in the medium, θ angle from the normal
