### Step-by-Step Solution: 1. **Definition of Dispersion**: Dispersion of light is defined as the optical phenomenon in which white light is separated into its constituent colors when it passes through a medium, such as a prism. 2. **Understanding White Light**: White light is composed of various colors, which can be observed in the spectrum. The primary colors of light are red, orange, yellow, green, blue, indigo, and violet (often remembered as ROYGBIV). ...
