To solve the problem of how to use two identical prisms so that a narrow beam of white light incident on one prism emerges from the second prism as white light, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Dispersion**: - When white light passes through a prism, it gets dispersed into its constituent colors (red, orange, yellow, green, blue, indigo, violet). This phenomenon occurs because different colors of light bend by different amounts when passing through the prism. 2. **Arrangement of Prisms**: ...
