WebAn optical fibre made up the glass with refractive index n 1 = 1.5 which is surrounded by another glass of refractive index n 2. Find the refractive index n 2 of the cladding such that the critical angle between the two cladding is 80°. Solution: Critical angle, θ = 80° Refractive index, n 1 = 1.5. Refractive index n 2 = ? WebAnd the angle of incidence is theta 1. And the angle of refraction is theta 2. And Snell's Law just tells us the ratio between v2 and the sin-- remember Soh Cah Toa, basic trig function-- and the sin of the angle of refraction is going to be equal to the ratio of v1 and the angle--the sin of the angle of incidence. Sin of theta 1.
