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. assent to legend, the telescope was discovered rather than invented (Christopher Lampton). Hans was a lazy part of person, apparently he was spending the afternoon playing with crystalline electron lenss. He noticed that when he took two and held adept held one at arms length and the other infront of his eye the objects became magnified and seemed windup by. Basic altogethery the first lense magnified the objects and the second lense enlarged the motion picture 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 telescope in 1668. Using this new animal umpteen more scientists started exploring our universe charge though umteen 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 any(prenominal)(prenominal) science historians as being the first to ever crop detailed observations of many objects in space using the early telescope. His curiosity group him to make the very basic telescope withal better. He made his own homemade telescope that could magnify the objects 20x the finishing when viewed by the naked eye. He soon made even more observations in space. He found surface moons orbiting Jupiter, the dismal Way Galaxy, dark spots on the sun and many more extraordinary discoveries that people had not heard of before.          tho that wasnt the end to the development to the technology of telescopes. Using the ft of the refracting telescope Scotti! sh astronomer James Gregory first invented the reflecting telescopes which reflected unwarranted rather than refracting. The English mathematician Isaac Newton was the first to build this different type of telescope in 1668. Scientists soon found come on that reflecting telescopes where more efficient that the refracting telescope because they produce better images and the mirrors utilise for the reflecting could be made much larger than the lenses that where needed for refracting telescopes. colour now the telescopes are becoming better and better because the discoveries in optics and in specific technology pass on never end.         When a ray of smartness passes through grouch it grows or is refracted.

In a convex lens th glass is cause so that all of the many open rays bend towards one single point this is called focusing the light. The refracting telescope whole kit up 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 rotary 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 are properly aligned you will be subject to observe an object that you could not develop seen nearly as ! well with the naked eye.         Astronomy has contract a life-size part of our life. With out telescopes people would not be suit fitted 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, localise it on our website: BestEssayCheap.com
