One advantage of reflecting telescopes is that the mirrors can be very big. Large mirrors allow reflecting telescopes to gather more light than refracting telescopes do. Another advantage is that curved mirrors are polished on their curved side, which prevents light from entering the glass. Thus any flaws in the glass do not affect the light. A third advantage is that mirrors can focus all colors of light to the same focal point. Therefore, reflecting telescopes allow all colors of light from an object to be seen in focus at the same time.
Size... a reflecting telescope with the same power as a refracting telescope is much shorter. This is because, in the reflecting telescope, the incoming light is bounced off mirrors (often more than once) which means the physical length is much shorter than an equivalent refracting model.
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
Not necessarily. Refracting telescopes can be large, but reflecting telescopes can also be quite large and often have larger apertures due to their design. The size of a telescope depends on its purpose and design specifications rather than whether it is refracting or reflecting.
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
Most modern telescopes are reflecting telescopes because reflecting telescopes are generally more cost-effective and easier to build at larger sizes compared to refracting telescopes. Reflecting telescopes also suffer less from chromatic aberration and can have a simpler design with fewer optical elements.
Radio
There are two main types of telescopes: refracting telescopes and reflecting telescopes. Refracting telescopes use lenses to gather and focus light, while reflecting telescopes use mirrors. Each type has its own advantages and disadvantages, but both are used to observe distant objects in space.
The most serious astronomical research, such as that done by the Hubble Space Telescope, is done with reflecting telescopes.
Reflecting Telescopes -uses a single or combination of curved mirrors to bring light to a focus and make an image.
Radio telescopes, refracting telescopes, and reflecting telescopes all use mirrors or lenses to collect and focus incoming electromagnetic radiation. The main difference is the wavelength of the radiation they are designed to study – radio telescopes focus on radio waves, refracting telescopes focus on visible light, and reflecting telescopes focus on a variety of wavelengths including visible light, ultraviolet, and infrared.
