Did alhazen discover light

Alhazen, also known as Ibn al-Haytham, did not discover light itself, as light is a fundamental aspect of the physical world. However, he made significant contributions to the understanding of optics and the behavior of light. His experiments and theories, particularly on how light travels and interacts with surfaces, laid the groundwork for modern optics and influenced later scientists. His work, especially the Book of Optics, is considered a seminal text in the study of light.
