Answered by | 22 Dec, 2013, 08:33: PM Practice Test Webinar Pre Board Assessment Concept Videos This video explains the types of curved mirrors and few of their uses. Their advantages are that they are more resistant to misalignment than reflector telescopes, the glass surface rarely needs cleaning, and the images are steadier and sharper because changes due to temperature and air currents are eliminated. Write two advantages of a reflecting telescope over a refracting telescope. If you are interested in astrophotography, purchasing a refractor is a better option because of its specialized optic design that captures deep space objects likeRead More 4.Only the reflecting side of the primary mirror needs to be perfectly shaped and smooth. (b) State the advantages of reflecting telescope over refracting telescope. The benefits of Newtonian reflecting telescopes over other telescopes include the following: Because the mirror can be fixed onto a metal plate, reflecting telescopes can be much bigger than refractors. Although the body is compact, the reflector telescope, especially the mid-sized and larger models, tends to be bulkier than the refractor telescopes. Answer (1 of 7): Refractors are actually the most expensive telescopes per aperture. That allows researchers to see what is happening within a dust cloud, a gas giant, or similar object. Even though reflectors are slightly more complicated for beginners, they will grow with you. Easy Solution Verified by Toppr There is no chromatic aberration as the objective is a mirror in reflecting type telescope. Refractor telescopes use a lens to gather and focus light. It Reflector telescopes do not suffer from chromatic aberration because all wavelengths will reflect off the mirror in the same way. 2. Answer (1 of 3): There are several. Mirrors can be very large. A lens works through the process of refraction. 2. 2. Which are advantages of reflecting telescopes? The Advantages and Disadvantages of Reflecting Telescopes. Superior performance in Advantages: The main advantage is reflector telescope can escape from chromatic aberration because wavelength does not effect reflection. WebAdvantages: 1. In order to get a bright image of a source, large mirrors are necessary, but it is easier to make large mirrors as compared to making large lenses. 2. The advantage of reflecting type of telescope are as follows: 1. Mirror It creates large magnification, Superior resolving power per inch of aperture, Its field of view is wide, Superior performance in inferior conditions image steadier, The image is free from aberration, not reflections or interruption of the light path, Long focal ratios can mean the use of longer focus, simpler, eyepieces Mirrors don't cause chromatic aberration and they are easier and cheaper to build large. Explanation: Advantages of reflecting telescope: These telescope are cheaper than the refractive telescope. A Mirrors The Advantages and Disadvantages of Reflecting Telescopes Mirror Advantage. To understand this, it helps to first understand how a lens works. In reflecting type telescope there is no chromatic aberration as the objective is a mirror. One of the next advantages of reflecting telescopes deals with aberration. The primary mirror is very stable because it is located at the back of the telescope and can be support in the back. 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). Reflecting telescopes have a few disadvantages as well. Because they are normally open, the mirrors have to be cleaned. Also, unless the mirrors and other optics are kept at the same temperature as the outside air, there will be air currents inside the telescope that will cause images to be fuzzy. Their advantages are that they are more resistant to misalignment than reflector telescopes, the glass surface rarely needs cleaning, and the images are steadier and sharper because changes due to temperature and air currents are eliminated.. Is it easier to make a Reflecting telescopes dont suffer from chromatic aberration. Reflecting telescopes use mirrors to collect and focus light, while 4. Allows all colors to be focused. WebThis arrangement is useful when optical equipment is being used that is too heavy to Reflecting telescopes use mirrors instead of lenses to collect light. They can go through these materials without being reflected or absorbed. Superior revolving power per inch of aperture. 1.There is no rainbow-like halo around the image. 4. Check all that apply. But what WebWhat are the advantages of a reflecting telescope over a refracting telescope? 5. These telescopes do require a delicate hand and must be moved from place to place with great care. Reflecting telescopes have a few disadvantages as well. Some of the reflector telescopes produce a distorted image. First, 3. Refractor telescopes are generally hardier than reflector telescopes so if you want to collapse your telescope and take it with you while camping or hiking to look at the night sky in remote places it would generally do better than a reflecting telescope. (a) Draw a schematic diagram of a reflecting telescope. 3. Also the image is brighter compared to the one formed in you dont have to look through the Earths atmosphere, For very detailed observations the atmosphere is pretty murky and horrible, You have Unlike other telescopes, radio telescopes are not blocked by celestial dust or debris. Reflecting telescopes have a number of other advantages over refractors. They form clear image of an object. Glass problems do not affect light entering in.
