Here's a breakdown:
* Euclid: In his book "Optica," Euclid described the Laws of Reflection, although he didn't explicitly state them as separate laws. He explained how light travels in straight lines and that the angle of incidence (the angle at which light strikes a surface) is equal to the angle of reflection (the angle at which light bounces off).
* Ibn al-Haytham (Alhazen): A 11th-century Arab scientist, Alhazen, further refined the understanding of reflection. He conducted experiments and formulated a more precise description of the Laws of Reflection.
While Euclid's work laid the foundation, Alhazen's contributions solidified our understanding of how light reflects off surfaces.
