What is the difference between a reflecting telescope a refracting telescope and a radio telescope?
Reflecting telescopes are usually designed to capture and concentrate light through the use of a large concave mirror which focuses the captured light on a smaller, flat mirror which in turn reflects it to the eye or a camera. Refracting telescopes use convex lenses to capture light and focus it where the eye or a camera is. Radio telescopes collect long wavelength radiation (radio waves and microwaves) and are all forms of reflecting telescope. The first telescopes were refracting telescopes, because the technology existed to form the needed sizes of convex lenses. Reflecting telescopes were developed later, when advancing technology provided the means of making very regular concave mirrors. All the largest modern telescopes are variations on the reflecting telescope design because it is easier to make and manage very large concave mirrors than it is to make lenses of equivalent light collecting power.
What is the difference between a refracting telescope and a?
A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses.There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope. A refractor telescope uses a glass lens as its objective. The glass lens is at the front of the telescope and light is bent (refracted) as it passes through the lens. A reflectortelescope uses a mirror as its objective. The mirror is close to the rear of the telescope and light is bounced off (reflected) as it strikes the mirror
What type of optical telescope has the potential to be made largest in power?
For amateurs, reflecting telescopes (with one parabolic and one flat mirror) can be made cheaply at very large sizes. For example, a $3000 telescope with lenses might be 4 inches wide and one with mirrors might be 16 inches wide. This also makes it possible to build massive reflectors for research purposes, like the planned 38-metre-wide E-ELT.
Why will many of the very large telescopes of the future make use of multiple mirrors?
Well the name of the game in telescopes is to collect as much light as possible. The more light you capture and concentrated the better and clearer the image. Multi-segment telescopes are designed to capture larges amount of light ad different optimal angles and channel them to a central focal point. Parabolic mirrors work efficiently at this naturally. However they are expensive and difficult to make properly, especially at large sizes. So having a multi-section mirror is cheaper and allows for a greater light concentration.Hope this helps
Reflecting telescopes are popular because they're than a refracting telescope?
Reflecting telescopes are popular because they are generally more compact and can be built in larger sizes without the issues of chromatic aberration that affect refracting telescopes. They use mirrors instead of lenses, which allows for a simpler design and easier manufacturing of large apertures. Additionally, mirrors can be supported from behind, reducing the risk of distortion that occurs with heavy lenses. Overall, these advantages make reflecting telescopes more versatile and effective for astronomical observations.
Why do scientist prefer refracting telescope over reflecting telescope?
Reflecting telescopes give a brighter, clearer image that refraactors in many cases. Add to that the fact that refractors become very impractical with objective lens sizes much above 40 inches, while reflectors can have mirrors of 200 inches and more.

Where can large mirrors be purchased?
Shopping for large mirrors online or at local IKEA store is a great place to find good deals. Simply Mirrors offers a wide selection on mirrors in various sizes and offer excellent deals.
Does Lowes sell bathroom vanities with big mirrors?
Yes, Lowes has bathroom vanities with all sorts of sizes of mirrors, including large ones. They also have in store displays so you can check them out.
Why same sizes of plane mirrors shows different sizes of images?
When two plane mirrors of the same size are placed at different angles to each other, the size of the images they create can appear different due to the way light reflects off them. The angle of incidence and reflection will affect how the rays of light bounce off the mirrors, resulting in variations in the size of the reflected images. Additionally, the position of the observer relative to the mirrors can also impact the perceived size of the images.
Why do images produced by two opposing flat mirrors apperar to be progressively smaller?
As the reflected image bounces back and forth between the two mirrors, each reflection results in a smaller image due to the angle of reflection. This creates the illusion of the image appearing progressively smaller as it moves further away from the mirrors.
How big can a mirror get?
Mirrors can be manufactured in various sizes depending on the requirements and limitations of the production process. Large mirrors can be several meters in diameter and are typically used for telescopes, solar concentrators, and architectural purposes. The largest mirrors, such as those used in telescopes, can be over 8 meters in diameter.
