Optical telescope

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

space. Although, they are normally quite large and expensive, these telescopes in particular have an advantage over average telescopes. Telescopes used in space can observe the whole sky and they can operate 24hrs a day, regardless of weather. This is an advantage to astronomers because it means they can do their work any time they need, making it easier for them to do research for work etc. Optical telescopes Optical telescopes keep an eye on visible light from space. Small ones allow non-specialists

Most people normally like touring places at one time or another. You will note that most tourist normally buy a pair of binoculars among other things. These equipment can help you bring objects that are far away closer to your eyes. This enables you to focus on them well and even distinguish them even though they are far away from you. You will note that not all people own a pair of binoculars. It is actually an investment for some people. If you choose to buy a pair of binoculars, you should consider

radio telescopes looking for far stars instead of a telescope?       First of all, what is a radio telescope? The first non-visual spectral region that was used extensively for astronomical observations was the radio frequency band. Telescopes observing at these wavelengths are commonly called radio telescopes. Radio telescopes may be made much larger than optical/infrared telescopes because the wavelengths of radio waves are much longer than wavelengths of optical light

Introduction to the History of space exploration To start the researching of the future of the space exploration the very first thing we should do is to look through a history of this particular topic. The main reason for this is because the history is a fundamental background for our understanding and knowledge. Aeronautical engineering does not have a long and deep history, compared to many things. Moreover, some information cannot be proved nowadays and that is why the only one thing that we can

Telescopes help us discover more about space and other things. There are many places to put a telescope space or on land. They all have there own advantages or disadvantages. A warm climate on Earth is a great place to put a telescope. Ground based telescopes are good for many reasons people can’t tamper with it, easier for maintenance, and they cost less than a space telescope. There are many other telescopes in space and on land like the Hubble Space Telescope and the Square Kilometer Array.

Microscopy and the Metric System Margaret E. Vorndam, M.S. Version 42-0090-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports

was the first chemical reaction humans learned to use and control? (worldbook.com) Chemistry has helped our world come up with new, advanced technology to benefit us all. Chemistry played a role in developing the periodic table, x-rays, and the telescope. Primarily, the Periodic Table of Elements was primarily thought to be developed by Dmitri Mendeleev. However, “Antoine Lavoisier first established the modern concept of the element in the late 1700s” (worldbook). Mendeleev published his version

Microscopy is a practical field for using microscopes to view object that cannot being seen with the naked eye or object that contained by the resolution range of the normal eye. There are two fundamentally different types of microscope. 1. ELECTRON MICROSCOPE:- Consist of electromagnetic lenses to focus a beam of light . - Having magnification power up to 200000. LIGHT MICROSCOPE:- consist of a single or a series of glass lenses to focus light in order to form an image. - Having maximum ability

larger than the eyepiece lens, more light would get through the telescope. The eyepiece lens will then reflect back the image to form an inverted, magnified virtual image in front of ~. For this experiment, the formulas used are the lens equations 1/f = 1/di + 1/do to find the focal lengths of the lenses, M = fo/fe for the prediction of magnification, and M = Hi/Ho for the actual measurement of magnification. According to theory, a telescope consisting two convex lenses acting as objective and eyepiece
