http://saclongchamp4.webs.com/ RKEY RKEY A telescope is a viewing instrument that utilizes the refraction or reflecting of light rays and allows for images to be brought closer,converse discount. This capturing of light is accomplished through a component that is called the objective,sac longchamp.
The objective is that part of the telescope which,longchamp pas cher 75278
http://conversepascher1.webs.com/,longchamp pas cher, through the captured light,longchamp, provides an image of the object that is being viewed,converse pas cher. Typically, the objective is either composed of a set of lenses or a concave mirror,converse all star.
Now,sac longchamp pas cher, think about the possibilities of utilizing liquid to mirror reflections back to our vision,converse all star. The concept of a liquid mirror would be similar to the experience of looking at your image in a pool of water,longchamp pas cher. However, a liquid mirror telescope would be used to peer into the depths of space,converse all star. At first glance the concept of a liquid mirror telescope seems like something that is a far-fetched and very futuristic,converse pas cher.
However,sac longchamp, the future is now as astronomers realize the potential of employing a liquid mirror telescope to take the place of a concave mirror that is typically found in a reflecting telescope.
History Of A Liquid Mirror Telescope
Isaac Newton in the 17th century was the first individual to go on record about the possibilities of a liquid mirror telescope,Telescope Component Innovations Liquid Mirrors,converse pas cher. In his studies,longchamp pas cher, he realized that when liquid is spun it forms a natural concave bowl-like shape. This spinning liquid would provide the same shape of the concave mirrors that are used in a reflective telescope,sac longchamp pas cher.
Unfortunately, his idea was ahead of its time,chaussures converse pas cher. The reason being is that the electric motor had not been invented,sac longchamp. The electric motor would have been needed to provide the rotation required to give the liquid its concave form,chaussure converse all star.
The first documented case of a liquid mirror telescope being used was in 1909,sac longchamp pas cher 11104

However,converse pas cher, it wasn’t until 1982 that a physicist by the name of Ermanno Borra modified the design to improve the performance of the liquid mirror telescope,prix converse. One such telescope is located in British Columbia,sac longchamp solde, Canada.
Structure Of A Liquid Mirror Telescope
Fortunately, today,sac longchamp pas cher,sac longchamp pas cher 74331
http://conversepascher1.webs.com/, all of the needed technology is available and has,sac longchamp pas cher, in fact,longchamp pas cher, brought the practical use of a liquid mirror telescope in to practice,sac longchamp. Specifically,sac longchamp pliage, the liquid that is used is 30 liters of mercury,sac longchamp. This mercury is poured into a concave dish that is built in segments,sac longchamp pas cher. The dish itself is manufactured from a durable plastic coupled with polyester. The frame that holds the dish is a light metal,achat converse.
The Process
In order to form the shape required to optimally provide the reflection needed,converse pas cher, the dish begins to spin,converse all star. The spinning speed is about 7 revolutions per minute. This speed is maintained so that the proper distribution of the mercury occurs.
Advantages And Disadvantages
The only disadvantage that has been demonstrated in the use of a liquid mirror telescope is the need for the dish to remain parallel. This is obviously due to the fact that if tilted the liquid would flow gravitationally to the end that is tilted downwards,converse all star.
The advantage is that the area of reflection is extremely large,longchamp pas cher. This larger area provides a greater capacity to capture more light which adds to the visibility of the object being viewed. In turn,sacs a main longchamp,Telescope Component Innovations Liquid Mirrors, this larger area of reflection allows for greater distances in the galaxy to be observed.
