Geometrical Optics
Geometrical Optics is a physics field studying light as straight rays. It includes principles like reflection, bouncing back of light from a surface like a mirror, and refraction, bending of light when it travels from one substance into another. These principles are vital for designing lenses, mirrors, and other optical devices.

Geometrical optics is the study of light's behavior as it travels in straight lines, particularly when interacting with lenses, mirrors, and other surfaces. It focuses on concepts like reflection (bouncing off surfaces) and refraction (bending as it passes through different materials). Using principles like the laws of reflection and Snell's law for refraction, geometrical optics helps us understand how images are formed in devices like cameras, glasses, and telescopes. This branch of optics emphasizes visual phenomena, making it essential for designing optical instruments and understanding visual perception in everyday life.
