Optics is the branch of physics that studies light and its interactions with matter. It explores how light behaves when it travels through different materials, such as air, water, and glass. This field helps us understand phenomena like reflection, refraction, and dispersion, which are essential for designing lenses and optical instruments. In everyday life, optics plays a crucial role in devices like cameras, microscopes, and glasses. These tools rely on the principles of optics to focus light and create clear images. By manipulating light, we can enhance our vision, explore the microscopic world, and capture memories through photography.
