WebMar 4, 2024 · Assuming that light travels from air to glass, the angle of incidence is 30°, and the angle of refraction is 20°. To calculate the refractive index, follow these steps: Identify the refractive index of air: n ₁ = 1. Modify Snell's law to find the refractive index of glass: n ₂ = n ₁sin (θ₁)/sin (θ₂). Enter data: n ₂ = 1×sin (30 ... WebDec 7, 2015 · 3.Draw a diagram to show refraction of a plane wave front incident on a convex lens and hence draw the refracted wave front.
