Book of Optics

The "Book of Optics," written by Ibn Al-Haytham in the 11th century, is a groundbreaking scientific work that explores the nature of light, vision, and optics. It explains how light travels, how eyes perceive images, and discusses phenomena like reflection and refraction. Ibn Al-Haytham used experiments and reasoning to challenge earlier ideas about vision, laying the foundation for modern optics and the scientific method. His work marked a shift from philosophical speculation to empirical investigation, significantly advancing our understanding of how we see and how light behaves.
