Brief History Binoculars were originally based from the telescope. Hans Lippershey‚ a spectacle maker‚ was the one who invented the telescope. Lippershey’s apprentice discovered that when holding 2 lenses in the same eye‚ with one lense distant from the other and looked through both‚ a far object seemed magnified or bigger. From there‚ Lippershey experimented with the lenses and was later known as telescope. Years later‚ Galileo Galilei developed Lippershey’s invention and was

Historical tools Telescope One of the most historical tools was the telescope. Which Galileo Galilei perfected the telescope that was originally created by Hans Lippershey. Most of the earliest versions of the telescope used a curved lens made of polished glass at the end of a tube to magnify objects to a factor of 3x. Galileo was the first person to actually see different masses far within space. It gave way for scientists to see stars‚ planets‚ and space. Also‚ the telescope helped scientists

The obvious assumptions that I held before reading the piece included that I would just be reading the step-by-step development of the telescope; I assumed that the test would be the standard stuff about how Galileo had always had such a fascination with lenses and how that lead to everything that followed happening. I also held belief that Galileo lived a fairly simple life. These are obviously

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

Although any telescope (or steadily-held binoculars) will allow the phases of Venus to be seen‚ the planet is a notoriously difficult one to observe‚ for three main reasons. Firstly‚ whenever the planet is visible (shortly before sunrise or after sunset) it is positioned at a low altitude (angle above the horizon) where it is immersed in haze and atmospheric turbulence‚ which adversely affects the quality of the image seen in the telescope. Consequently most telescopic observers prefer to view the

Lab Title: Microscopy Objective: To learn how to use and care for a microscope and to know the parts of a compound microscope and to efficiently use the microscope to focus on specimen. Introduction A microscope is an optical instrument used for viewing very small objects‚ typically magnified several hundred times. It consist of different lenses such as: Scanning = 4X‚ Low power = 10X‚ High power = 40 or 43X‚ Oil Immersion = 100X. A microscope is an instrument

A microscope (from the Ancient Greek: μικρός‚ mikrós‚ "small" and σκοπεῖν‚ skopeîn‚ "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy.Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes‚ the most common and first to be invented is theoptical microscope which uses light to image the sample. Other major types of microscopes

If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult
