Rigby) WebYour telescope is a "refracting telescope," because it uses lenses to help gather more light than your eye could possibly do on its own. The scope uses two lenses to bend light, which makes an object appear closer than it really is. The size of the image produced by the telescope depends on the curvature of the lenses.

Web29 de nov. de 2024 · 0. Telescopes are about magnifying angles. They make some distant target that subtends an angle θ look like it subtends n θ, appearing n times larger/closer. If you focus on that idea, telescopes are easier to understand. The object lens makes an image of the target. Imagine the top and bottom of that. http://physics.wm.edu/~labs/astro/astro_manual/ch8.pdf dark hair white highlights
