........................ is the splitting of white light into its component colours.

• Dispersion of light

• Reflection of light

• Refraction of light

• Diffusion of light

........................ is the light that is scattered, causing it to fall on the crop from all sides. The light is evenly distributed, leaving no sharp shadows.
