Comparison Between Optical Telescope Systems And Modern...

Background knowledge: The topic of this investigation is to compare and contrast three different optical telescope systems that are used in modern day times. The three main telescope systems that will be focused on in this report will be reflecting, refracting and cassegrain which is a combination of both and how different types of error such as aberration effect the telescopes ability to capture an image and the quality of the image it produces. Reflecting telescopes use mirrors to reflect incoming light rays onto a secondary mirror which magnifies it through an eye piece to form an image. (BBC, 2015) When light rays come in contact with the mirror they are called the incident ray and then when the ray reflects back off the mirror it is then called the reflected ray. As the light rays hit and leave the mirror at particular angles these are titled angle of incidence and angle of reflection which can be seen in the figure 2 below. By the first law of reflection it is assumed that the angle of reflection is equal to the angle of incidence. This would only be true for totally reflective flat surfaces. When light rays come into contact with convex and concave mirrors parallel to the normal they are reflected onto a ‘focal point’. To find the focal point of a mirror, the mirror formula can be used. 1/f=1/u+1/v Where ‘f’ is the focal length, ‘u’ is the objects actual distance away from the mirror and ‘v’ is the distance the image is formed from the mirror.

His main field of study is cosmic magnetism which also encompasses the study of supernova remnants. Because magnetic fields are not visible to the naked eye or regular telescopes, Gaensler’s team must use radio telescopes to view the polarised radiation being emitted. By using radio telescopes to view the fields, they are able to view the â€Å"Faraday Rotation† of distant objects and galaxies. Michael Faraday showed that a magnet is capable of producing a rotational motion in a conductorRead MoreElectronic Mass Planets Orbiting The Pulsar Psr B125710312 Words   |  42 Pagesof several terrestrial-mass planets orbiting the pulsar PSR B1257+12.[31] The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods such as the transit method and the radial-velocity method.
