Applications of Optics

Optics is the study of light and how it behaves and interacts with matter. It provides the principles behind many of the technologies we use daily. It also helps us understand phenomena such as reflection, refraction, and dispersion. In this article, we are going to learn some real-life applications of optics.

Optics Definition

Optics is a branch of physics that focuses on the study of light and its properties. It explores how light behaves when it interacts with different materials and travels through various mediums. The field covers a wide range of phenomena, including how light bends, bounces, scatters, and is absorbed by objects.

Reflection and refraction are two key processes in optics. Reflection occurs when light bounces off a surface, while refraction happens when light passes through a substance and bends. Both processes are important for optical devices like mirrors, lenses, and prisms to function.
