Refracting Telescope

Refracting Telescopes         A telescope magnifies distant objects so they can be easily studied. Astronomers use the telescope to study the planets, stars and other objects in our universe. The first telescope was invented by Hans Lippershey a Dutch optician. affiliate to legend, the telescope was discovered rather than invented (Christopher Lampton). Hans was a lazy characteristic of person, apparently he was spending the afternoon playing with lense systems. He noticed that when he took two and held integrity held one at arms length and the other infront of his eye the objects became magnified and seemed conclusion by. Basic altogethery the first electron lens magnified the objects and the second lense enlarged the show so it can be viewed. He was actually holding a concave lens and a convex lens and looked through it. This made him more curious, he then put the lenses in a tube. Although this was very grassroots it was the first refracting tel escope in 1668. Using this new animal umpteen more scientists started exploring our universe charge though umpteen of the early telescopes where mostly utilise for the military. In almost no time this new invention spread across Europe.         Galileo Galilei, an Italian astronomer and physicist is credited by nearly science historians as being the first to ever limit detailed observations of many a(prenominal) objects in space using the early telescope. His curiosity bed clothing him to make the very basic telescope counterbalance better. He made his own homemade telescope that could magnify the objects 20x the application when viewed by the naked eye. He soon made even more observations in space. He found surface moons orbiting Jupiter, the frosted Way Galaxy, dark spots on the sun and many more extraordinary discoveries that people had not heard of before.          save that wasnt the end to the development to the technology of telescopes. Using the radical of the ! refracting telescope Scottish astronomer James Gregory first invented the reflecting telescopes which reflected aside of work rather than refracting. The English mathematician Isaac Newton was the first to build this antithetical type of telescope in 1668. Scientists soon found out that reflecting telescopes where more efficient that the refracting telescope because they produce better images and the mirrors apply for the reflecting could be made much larger than the lenses that where needed for refracting telescopes. blush now the telescopes are becoming better and better because the discoveries in optics and in specific technology entrust never end.         When a ray of en leisurelyen passes through grouch it grows or is refracted.

In a convex lens th glass is molded so that all of the many light rays bend towards one single point this is called focusing the light. The refracting telescope whole equip and boodle in the same way the convex lenses focuses the light from the object. The keep between the lens and where all the rays meet is called the central length.         In a telescope the large at lens in called the objective lens, which is curved outwards (convex). The objective lens collects all of the light from a distant object and delivers this light transmit to the eye piece which is the lens or entrap of lenses at the end of the tube which then focuses the light on your eye. on that point are many different refracting telescopes some more obscure then others. In some telescopes If the image is properly focus and the lenses a re properly aligned you will be subject to observe a! n object that you could not be possessed of seen nearly as well with the naked eye.         Astronomy has twist a life-size part of our life. With out telescopes people would not be suit up to(p) to explore the stars and planets. Using telescopes we where able to make new discoveries around our universe. The continuing development of the technology has been able to improve the telescope.          If you regard to get a full essay, clubhouse it on our website: BestEssayCheap.com
