Ibn al-Haytham does not give the impression that he was seeking a law which he failed to discover; but his "explanation" of refraction certainly forms part of the history of the formulation of the refraction law.
Ibn al-Haytham ay hindi magbigay ng impression na siya ay naghahanap ng isang batas na kung saan siya ay nabigo upang matuklasan; ngunit ang kanyang "paliwanag" nang repraksyon tiyak forms bahagi ng kasaysayan ng pagbabalangkas ng repraksyon batas.
