To draw a ray diagram showing the dispersion of white light through a prism, follow these steps: ### Step-by-Step Solution: 1. **Draw the Prism**: Begin by sketching a triangular prism. The prism should have two refracting surfaces and a base. Label the vertices as A, B, and C, where A and B are the refracting surfaces. 2. **Draw the Incident Ray**: Draw a straight line representing a narrow beam of white light approaching the prism. This line should strike one of the refracting surfaces (let's say surface AB) at an angle. Label this ray as "Incident Ray". ...
