MICROSCOPY Objective: 1. To learn how to use both a dissecting and a compound microscope effectively and efficiently (lighting‚ focus‚ magnification‚ resolution)‚ and to practice manipulating small organisms Principals: 1. The smallest object viewable under a compound light microscope is limited by resolution or resolving power (ability to distinguish between two nearby points) and not magnification. 2. Mircoscope resolution is limited by the wavelength of the source of illumination (visible

Microscope * Head/Body houses the optical parts in the upper part of the microscope * Base of the microscope supports the microscope and houses the illuminator * Arm connects to the base and supports the microscope head. It is also used to carry the microscope. * Eyepiece or Ocular is what you look through at the top of the microscope. Typically‚ standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available‚ typically from 5x-30x. * Eyepiece

The aperture of a telescope is several times larger than the aperture of human eye so that the objects that cannot be normally seen by unaided eye can be seen. Light- gathering power of a telescope is proportional to the area of its aperture and hence depends on the square of the radius of the mirror. Therefore a 20 cm diameter telescope collects four times more photons than a 10 cm diameter telescope. Pg1 Labelled Picture Pg2 The Principle of Sight Optical telescopes are divided into

History of Telescopes We have all heard about telescopes and how useful they are in our present time. We also generally associate telescopes to astronomy like the Hubble Space Telescope. There is a rich history behind its invention and its further progression which we will now discuss. The first type of telescope invented was an optical telescope. This telescope has three designs‚ namely‚ refracting telescopes‚ reflecting telescopes and catadioptric telescopes (refracting and reflecting combined)

Introduction The Hubble Space telescope has been Orbiting the Earth for over two decades‚ Hubble has helped to answer some of the most compelling astronomical questions of our time – and uncovered mysteries we never knew existed. Investigating everything from black holes to planets around other stars‚ Hubble has changed the face of astronomy‚ ushering in a new chapter of humanity’s exploration of the universe. Although named to honor astronomer Edwin Hubble‚ the telescope was championed by astronomer

The Hubble Space Telescope was launched after a two-year delay on April 24th‚ 1990 from the space shuttle Discovery. This telescope has a length of 13.2 meters and a weight at launch that was 11‚110 kg. It is a space-based optical reflective telescope that observes distant and faint objects. (NASA) One of the most important discoveries of the Hubble Space Telescope has to be that it has revealed the age of the universe to be 13 to 14 billion years old‚ this was a huge improvement from the earth based

2015 Telescopes in Astronomy Telescopes have proven to be one of the greatest inventions in the science of astronomy. This instrument‚ which makes far-away objects more visible has facilitated both learning about and understanding our universe. This paper will discuss the importance of telescopes‚ their three major designs‚ and the strengths and weaknesses of different locations for telescopes. In addition‚ this paper will discuss the frequencies of light and the role they play in telescopes. Without
