Explanation

• Dispersion is the optical phenomenon where white light is split into its constituent colors, also known as a spectrum.
• This occurs when light passes through a medium with a refractive index that varies with wavelength, such as a prism.

The process of dispersion involves two stages:

1. Refraction (bending of light)
2. Separation of colors (splitting into distinct colors)

The seven distinct colors that make up the visible spectrum, in order, are:

1. Red
2. Orange
3. Yellow
4. Green
5. Blue
6. Indigo
7. Violet
