AI Generated Solution

To solve the problem, we need to find the angle of deviation (Δ) of a ray of light incident normally on one face of a prism with an apex angle of 30 degrees and a refractive index of √2. ### Step-by-Step Solution: 1. **Understanding the Incident Ray**: - The ray of light is incident normally on one of the faces of the prism. This means that the angle of incidence (i) at the first face is 0 degrees. 2. **Identify the Apex Angle**: ...
