Answer 1

Ibn al-Haytham:

Ibn al-Haytham made huge advances in optics, science, and space science. His work on optics was described by a solid accentuation on painstakingly planned examinations to test speculations and theories.

Ibn al-Haytham is viewed as the dad of optics for his compelling The Book of Optics, which accurately clarified and demonstrated the cutting edge intromission hypothesis of visual observation, and for his analyses on optics, remembering tests for focal points, mirrors, refraction, reflection, and the scattering of light. Ibn al-Haytham's most significant work is Kitāb al-manāẓir ("Optics").

Despite the fact that it gives some impact from Ptolemy's second century promotion Optics, it contains the right model of vision: the latent gathering by the eyes of light beams reflected from objects, not a functioning spread of light beams from the eyes.

In his incredible exercise manual of Optics, Alhazen accurately distinguished that our eyes don't emanate beams. He contended that light influences the eye – for instance, we can harm our eyes by taking a gander at the sun – yet our eyes don't influence light.
