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.

What is the main question raised about Legolas's vision?

• Whether he can see in the dark

• His ability to see underwater

• If he can see colors

• The feasibility of seeing distant objects clearly

What is the primary reason light does not travel in perfectly straight lines?

• It is a wave

• It is affected by gravity

• It is absorbed by air

• It is reflected by surfaces

What is the term used to describe the blurring effect caused by light passing through small openings?

• Refraction

• Reflection

• Diffraction

• Dispersion

How does diffraction affect the ability to distinguish small details at a distance?

• It changes the color of the details

• It blurs the details

• It magnifies the details

• It enhances the details

Why would seeing in ultraviolet light not help Legolas in distinguishing distant objects?

• UV light is absorbed by air

• UV light causes eye damage

• UV light is too bright

• UV light is invisible to humans
