Which consequence emerged when Alhazen studied light refraction?

💡 Explanation

Alhazen's experimentations led to the discovery of camera obscura operation involving the principle of rectilinear propagation, because small apertures cause images to invert inside darkened spaces; therefore, pinhole projection occurred, rather than alternative principles like light collection for timekeeping.
