### Step-by-Step Solution: 1. **Understanding Dispersion**: Dispersion occurs when white light is separated into its constituent colors (spectrum) as it passes through a medium, such as a prism. This happens because different colors of light travel at different speeds in a medium. 2. **Thin Prism and Light**: When white light enters a thin prism, it bends or refracts at the surfaces of the prism. The amount of bending depends on the wavelength of the light. 3. **Angular Dispersion**: The angular dispersion is the angle between the emergent rays of the violet and red light. Violet light bends more than red light because it has a shorter wavelength. ...
