A laver of liquid 8 floats on liquid A. A ray of light begins in liquid A and undergoes total internal reflection at the interface between the Liquids when the angle of incidence exceeds 34.9°. When liquid 8 is replaced with liquid C, total internal reflection occurs for the angle of incidence greater than 51.2°. Find the ratio nₒ/nc of the refractive indices of liquids B and C
