= Topic 1 Lenses and Refracting Telescopes = In the exam you are expected to know about: * Principal focus, focal length of converging lens * power = 1/f * Formation of images by a converging lens * Ray diagrams * Lens formula: 1/f = 1/u + 1/v * Astronomical telescope consisting of two converging lenses * Ray diagram to show the image formation in normal adjustment * Angular magnification in normal adjustment * M = angle subtended by image at eyeangle subtended by object at unaided eye * Focal lengths of the lenses * M = fo/fe * *: Refractors were the earliest type of optical telescope. The first practical refracting telescopes appeared in the Netherlands in about 1608, and were credited to three individuals, Hans Lippershey and Zacharias Janssen, spectacle-makers in Middelburg, and Jacob Metius of Alkmaar also known as Jacob Adriaanszoon. Galileo, happening to be in Venice in about the month of May 1609, heard of the invention and constructed a much improved version of his own based on his understanding of the effects of refraction. Galileo then communicated the details of his invention to the public, and presented the instrument itself to the Doge Leonardo Donato, sitting in full council. Galileo may thus claim to have invented the refracting telescope independently, but not until he had heard that others had done so

∙ 14y agoHubbleSite.org is one of the best sources for info on the Hubble Space Telescope. Another is http://www.stsci.edu/hst/ for more technical stuff. The Chandra X-Ray Telescope is managed by Harvard University.

∙ 12y agonearer and clearer vision and the ability to look alo lot futher then the naked eye sometimes you can get one that inables you to look at other planets
-my thought is he wants more than the answer the last guy gave above. Being honest I don't have one but it would be best for a new answer if anyone knows one
Sincerly Gloogh I do not want to give buy real name away to strangers, Apologies.

∙ 10y agoThe Hubble and Chandra telescopes have helped scientists find out more about our solar systems because they are both very powerful. These are the first telescopes that have allowed us to see planets that are very far away.

What type of telescope is the hubble telescope?
The Hubble telescope was a basic reflector telescope with a 94.5 ft mirror. The Hubble collects light though its open end, the primary mirror reflects the light to a secondary mirror that then reflects the light through a hole in the primary mirror to a focal point of the instruments or eyes of the Hubble.
What was the hubble space telescope named after?
The Hubble Space Telescope was named after Edwin Hubble.
What is the name of the telescope that they use to see galaxies?
the hubble telescope edwin hubble :)
Did the Americans launch the Hubble telescope?
Yes, the Americans built launched the Hubble telescope.
Who came up with the idea for the hubble space telescope?
The focal point of all Hubble Space Telescope (HST) activities is the Space Telescope Operations Control Center (STOCC) at NASA's Goddard Space Flight Center in Greenbelt, Md., where the orbiting observatory is managed.
What telescope took information on Neptune?
The Hubble space Telescope
Is Hubble the only telescope orbiting earth?
No, there's a great number of highly specialized telescopes in orbit. The most famous ones apart from Hubble are the Spitzer Space Telescope (for infrared) and the Chandra (for X-rays).
What are NASA's the best observatories?
There are four: Hubble Space Telescope, Compton Gamma Ray Observatory, Chandra X-ray Observatory, and the Spitzer Space Telescope.

Did Edwin Hubble have anything to do with the Hubble Space Telescope?
No, Edwin Hubble had nothing directly to do with the Hubble Telescope, it was named for him because he profoundly changed the understanding of the nature of the universe. Hubble died before the the physical exploration of space began. Hubble also created his own Hubble telescope back in 1929 but it is not the orbiting Hubble telescope. Go to the NASA website for more information.
What was the hubble space telescope named after?
The Hubble Space Telescope was named after Edwin Hubble.
Who was the hubble telescope named after?
The Hubble Telescope was named after its designer Edwin Hubble.
What was Edwin Hubble know for?
Telescope, hence the hubble telescope!
What is the Hubble Telescope?
The Hubble Telescope is a telescope that orbits the earth every 97 minutes
What telescope is replacing the Hubble telescope?
The replacement for the Hubble is called the James Webb Space Telescope.
What is the Comparison between Hubble and Galileo telescope?
what is the comparison between Hubble telescope and Galileo telescope
Why the Hubble telescope is unique?
The Hubble telescope is unique because it was the first space telescope. Also, the Hubble is one of the largest and most versatile.
