The refractive index of the material of ...

The refractive index of the material of a prism of refracting angle `45^@` is `1.6` for a certain monochromatic ray. What will be the minimum angle of incidence of this ray on the prism so that no TIR takes place as the ray comes out of the prism.

To solve the problem step by step, we will follow these steps: ### Step 1: Understand the Problem We need to find the minimum angle of incidence (I) for a monochromatic ray entering a prism with a refracting angle of 45° and a refractive index of 1.6, such that no Total Internal Reflection (TIR) occurs when the ray exits the prism. ### Step 2: Determine the Critical Angle The critical angle (θc) can be calculated using the formula: \[ ...
