Which figure is associated with advancing optics and the camera obscura concept in early science?

• A. Alhazen
• B. Aristotle
• C. Michelangelo
• D. Shakr-e Sukteh Pot Images

Answer: (B)

Advancing optics and the camera obscura concept is tied to someone who approached vision with careful experiments about how light travels. That figure is Ibn al-Haytham, known in the West as Alhazen. He laid down early, systematic principles of optics, showing that light travels in straight lines and that the image formed by a small hole in a dark chamber is an inverted projection of the outside world onto the opposite wall. This idea is the essence of the camera obscura, a device that helps explain how images are formed by light rather than by the eye’s workings alone. Alhazen’s emphasis on observation and experimental method helped shift optics from merely philosophical speculation toward testable science, influencing later scholars and the development of imaging technologies.

Aristotle contributed to theories of vision in ancient philosophy, but he did not advance the camera obscura concept in the way Alhazen did. Michelangelo was a Renaissance artist whose work emphasized painting and anatomy rather than optical theory, and the remaining option is not a recognized figure in this scientific lineage.
