WebFeb 13, 2024 · Below points explain how to find the angle of refraction through glass: Find the refractive index of air, n₁ = 1.000293. Establish the glass refraction index, n₂ = 1.52. Determine the angle of incidence, θ₁. We'll take it to be 45°. Rearrange Snell's law to calculate the angle of refraction, θ₂: sin (θ₂) = n₁sin (θ₁)/n₂. WebApr 10, 2024 · Refraction through rectangular glass slab with parallel faces: The refraction takes place at both air-glass interface and glass-air interface has the following characteristics: When a light ray travels from air to glass, the angle of incidence is greater than angle of refraction as ray bends towards normal. nwb agencia
