To solve the problem step by step, we will analyze the situation involving the prism, the angle of incidence, and the refractive index. ### Step-by-Step Solution: 1. **Understanding the Prism Configuration**: - We have a prism with an angle of \( A = 30^\circ \). - One face of the prism is silvered, which means it acts like a mirror for the light ray that hits it. ...
