Alayer of liquid b 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 32.0°. when liquid b is replaced with liquid c, total internal reflection occurs for angles of incidence greater than 46.0°. find the ratio nb/nc of the refractive indices of liquids b and c.

0.737

Explanation:

= Refractive indices of liquid A

= Refractive indices of liquid B

= Refractive indices of liquid C

Consider the total internal reflection at interface of liquid A and liquid B

= Angle of incidence = 32.0

Using Snell's law for total internal reflection

Consider the total internal reflection at interface of liquid A and liquid C

= Angle of incidence = 46

Using Snell's law for total internal reflection

Ratio is hence given as
