This document contains questions about light, color, and sight. It discusses the formation of images using plane mirrors, lenses, and optical instruments like microscopes and telescopes. Characteristics of images formed in different locations relative to the focal point are described. Dispersion of light through prisms and scattering of light by particles in the atmosphere are also addressed. The document asks about primary and secondary colors obtained through mixing.
