Geometrical Optics

Geometrical Optics studies the behavior and the properties of light. It basically deals with light and vision. The main concepts of geometrical Optics are nature, generation, propagation, transmission, absorption, diffusion, reflection, and refraction of light. The further modern usage of light, such as transport of information signals, would redefine Optics, where eye is no longer the only final terminal of light. Applying the main concepts of Optics would help any trainee to effectively operate and handle optical instruments.
