Optics (branch of physics)

Optics is the branch of physics that studies how light behaves and interacts with matter. It covers phenomena like reflection, refraction, dispersion, and diffraction, which explain how we see objects, how lenses focus light, and how colors and optical devices work. Understanding optics involves examining the wave and particle nature of light, and how it can be controlled and used in technologies such as eyeglasses, microscopes, cameras, and lasers. Overall, optics helps us understand the behavior of light in everyday life and in advanced scientific and technological applications.
