How Far Can Legolas See?

The video explores the claim by Legolas, an elf, of seeing distant objects with great detail, questioning the feasibility of such vision given human limitations. It delves into the nature of light as a wave and the concept of diffraction, which blurs images when light passes through small openings. The video explains how diffraction limits human vision, making it impossible to see small details at great distances. It also discusses the potential for ultraviolet vision to improve clarity, though atmospheric absorption poses challenges. Finally, it illustrates diffraction effects in photography.
