Telescopes. How do they work?. 1. History. 2. Lenses & Hardware. 3. Reflecting Telescopes. 4. Refracting Telescopes. History. Hans Lippershey Middleburg, Holland invented the refractor telescope in 1608 Galileo
Telescopes!. Gazing into the Night Sky. What would Galileo do if he could see things we can see through a telescope?. There are many inhospitable places on Earth…but nothing like it is in Space!
TELESCOPES. Portals of Discovery. Telescopes: Portals of Discovery The Eye: The Everyday Light Sensor. The eye is made of a lens, pupil, and a retina The pupil allows a certain amount of light to enter the eye.
Telescopes. Galileo first used a telescope to observe the sky in 1610 The main function of a telescope is to gather faint light from an astronomical source and to focus that light into an image The light gathering ability of a telescope is defined by its diameter or aperture
Telescopes. Amateur and Professional. Galileo 1609. The Moon as a World. Jupiter has Moons. Refracting telescopes. Long focus refractors were awkward but suffered less from chromatic aberration. Isaac Newton’s reflecting telescope. Mirrors do not have chromatic aberration.
Telescopes. Forms of Radiation. Electromagnetic radiation - energy that travels across distances as certain types of waves (ex: visible light) Electromagnetic radiation travels in all directions throughout space. Forms of Radiation.
Telescopes. Refractors and Reflectors Various Designs Important Properties Modern Advances Beyond Visible Light. Basic Optics - Refraction. Light is bent or refracted when it changes speed going through a lens or prism. Where the refracted rays meet is the “focal point.”
Telescopes. Physics 113 Goderya. Chapter(s): 6 Learning Outcomes:. Optical Telescopes. Astronomers use telescopes to gather more light from astronomical objects. The larger the telescope, the more light it gathers. Refracting/Reflecting Telescopes.
Telescopes. Galileo 1609. The Moon as a World. Jupiter has Moons. Refracting telescopes. Isaac Newton’s reflecting telescope. Reflecting telescope. Objective mirrors instead of lenses. Three Powers. Magnifying Resolving Light Gathering. Magnifying Power.
2) absorption when you place your hand near a light bulb, ... light to pass through (where some fraction is also absorbed) 4) reflection/scattering light can bounce off ...
