Which phenomenon allowed Ibn al-Haytham (Alhazen) to accurately describe image formation in his 'Book of Optics' (Kitab al-Manazir)?

💡 Explanation

When light interacts with objects, rectilinear propagation of light rays occurs because light travels in straight lines from the object to the eye, forming an interpretable image per Alhazen's experiments. Therefore rectilinear propagation enables this understanding, rather than duality, aberration, or diffraction relating to more complex or later-discovered optical phenomena.
