Optics in physics is essential in understanding how humans visualize the world. Studying the behavior of light allowed humans to construct and use optical devices, such as telescopes, microscopes, and cameras. These devices opened more opportunities to learn about other fields of study. Optics also paved the way for producing groundbreaking inventions (e.g., lasers and holography), some of which are used in visual communication and medical techniques. The discovery of fiber optics also played a crucial role on faster communication and transmission of information.

Geometrical and physical optics requires a strong foundation in basic mathematical concepts and a grasp of the principles of light propagation. Here are the key prerequisites:
Mathematical Concepts:
Ø Trigonometry: A solid understanding of trigonometric functions, identities, and their applications is crucial.
Ø Algebra: Proficiency in algebraic manipulation and equation solving is essential.
Ø Geometry: Knowledge of basic geometric shapes, properties, and theorems is necessary.
Physics Concepts:
Ø Reflection and Refraction: Understanding the laws of reflection and refraction, as well as the properties of mirrors and lenses, is fundamental.
Ø Ray Diagrams: Ability to draw accurate ray diagrams to visualize the path of light through optical
systems.
