Q & A: How Do Telescopes Work? | Department of Physics ...

Refracting telescopes work by using two lenses to focus the light and make it look like the object is closer to you than it really is. Both lenses are in a shape that's called 'convex'. Convex lenses work by bending light inwards (like in the diagram).

telescope - Reflecting telescopes | Britannica

Reflecting telescopes. Reflectors are used not only to examine the visible region of the electromagnetic spectrum but also to explore both the shorter- and longer-wavelength regions adjacent to it (i.e., the ultraviolet and the infrared).The name of this type of instrument is derived from the fact that the primary mirror reflects the light back to a focus instead of refracting it.

How Does A Refracting Telescope Work? | All Things Backyard

These are the structural components of a refracting telescope: Objective Lens: Among the 2 lenses, the larger one is the objective lens. The objective lens sits at the front of the telescope and is responsible for gathering lights. The larger the objective lens is, the more light it can collect. As a result, the image will be crisper and sharper.

Reflecting Telescopes use a concave primary mirror to collect light and form an image. In the Newtonian type of reflector, light is reflected by a small, flat secondary mirror to the side of the main tube for observation of the image. In the refracting telescope, light is collected by a 2-element objective lens and brought to a focus at F.
