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)

Binoculars are used for viewing far objects like buildings‚ birds‚ and much more. Other information related to the devices Telescope The earliest recorded working telescopes were the refracting telescopes that appeared in the Netherlands in 1608. Their development is credited to three individuals: Hans Lippershey‚ Zacharias Janssen and Jacob Metius. Binoculars The telescope was introduced to astronomy in 1609 by the great Italian scientist Galileo Galilei. Periscope In 1854 Hippolyte Marié-Davy

Introduction The telescope is an instrument which increases our ability to observe far away objects through the collection of electromagnetic radiation‚ the most prevalent type of telescope is the optical telescope which collects light‚ however there are other kinds of telescopes which collect UV and X -Rays. Optical telescopes use lenses to redirect light to a specified point. Different lenses are used for different magnifications of celestial objects. This essay will be mainly discussing

A few weeks ago NASA approved the work on the space telescope Transiting Exoplanet Survey Satellite‚ TESS‚ wich will be sent to orbit on 2017 with the mission of finding exoplanets. Exoplanets are planets that orbit a star that is not our sun‚ and until now scientists have discovered over 800 of them‚ mainly thanks to the Kepler telescope wich began working in 2009. TESS goal is to identify planets within the habitable zones of nearby stars. This mainly means planets with a solid crust and with temperatures

Galileo Galilei | Galileo Galilei was the first astronomer to use a telescope to study the heavens. Galileo made a number of observations that finally helped convince people that the Sun-centered solar system model (the heliocentric model)‚ as proposed by Copernicus‚ was correct. What is a Galilean telescope? The original design Galileo Galilei came up with in 1609 is commonly called a Galilean telescope. Galileo’s telescope with which Jupiter’s moons could be observed was made with a plano convex

Technology Devices to Overcome the Limitations of Sight and Hearing Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Most of the limitation of sight can be overcome with the help of certain optical instruments such as magnifying glass‚ microscope‚ binoculars and others. The range of frequency of hearing in human 20 Hz to 20 000 Hz. It was different according to the age of a person. Hearing limitations can be overcome by using devices such as

INTRODUCTION Defects of Hearing •Hearing defects means ear is not working correctly or as well as it should. •It may occur in more than one part of the ear. •1. DEAF-full or partial decrease in the ability to detect or understand sounds. Deaf usually caused by : - Eardrum is torn-cannot function - Ossicle bone fused together-can’t vibrate - Auditory nerve damaged by loud sound - Cochlea damage due to sickness/ drugs •2. Temporary hearing loss-build-up of earwax •3. Presbycusis- hearing loss
