How much greater is the light-collecting area of one of the 10-meter Keck telescopes than that of the 5-meter Hale telescope?
A 1 m telescope has a collecting area of pi x 1 x 1 = 1 piA 3 m telescope has a collecting area of pi x 3 x 3 = 9 pi.Therefore, the bigger telescope collects 9 times as much light.
What was the major contribution that Johann muller gave to the science of astronomy?
Huygens proposed as an explanation for Saturn's apparently unusual shape a thin, flat ring around the planet, which he later proved (though later observation would show he was not entirely correct about Saturn's 'ring'), along with discovering the moon Titan, using a telescope he designed. He also notably studied several nebulae, including the Orion nebula, which now retains a region named in his honour. He was also an early speculator on the existence of extraterrestrial life, writing a posthumously published work Cosmotheoros speculating on the conditions necessary for live to exist on a planet, focusing on ambient water and light. In honour of his substantial contributions to the world of science, including astronomy, several missions, mission vehicles, and astronomical objects are named after Huygens.
What does the word telescope mean in greek language?
A telescope is an instrument with curved mirrors and lenses to make distant objects appear closer.
What is used for final focusing on a microscope?
fine adjustment
What does the fine adjustment of a compound microscope do?
it is used for final focusing.
What will an astronomer see if A fly has gotten onto the object lens of a telescope What will an observer looking through the telescope see?
no detail on the fly, as (depending on the design) an astronomical telescope has trouble focusing any closer than about 8 metres, let alone an object actually on the objective lens. I imagine the view would be tarnished by a black smudge in the Field of view.
Telescopes that use lenses for focusing light are called what telescopes?
That telescope you are refering to is called a refracting telescope.
What is the purpose of the newtonian reflecting telescope?
Gathering and focusing light from distant objects.
How do scientists adjust the telescopes to get a view of the astronomical objects?
It's simple in/out focus, just like focusing a pair of binoculars at a football game. That is oversimplifying, of course (it takes several hours of computer commands to perfectly focus the Hubble Space Telescope, for example), but that is still the basics of it.
The word skipping technique enables you to figure out?
The word skipping technique involves focusing on the main idea of a passage.
Schuster''s technique for focusing the prism spectrometer?
yes this is an impotent method for focusing the spectrometer in-order to obtain the appropriate readings.
The word-skipping technique enables you to figure out?
The word skipping technique involves focusing on the main idea of a passage.
An instrument that produces images by focusing light rays is called a?
a magnifying glass, a telescope or microscope all do this.
What is refractors?
A refractor is a telescope whose principal focusing element is a lens and collects lots of light from a distant object and brings that light, or image, to a point or focus.
What is the largest single radio telescope?
Arecibo, Puerto Rico . . . largest curved focusing dish on Earth, 305 meters diameter. (1,000 ft, 0.19 mile)
What is the definition of the music term technique?
Definitions vary, but here's one: It's a musician's (instrumentalist or singer) control over their instrument or voice. It takes years of practice to develop technique, and can be acquired with specific exercises focusing on different aspects of technique (these vary depending on the instrument). A player with exceptional technique can play both fast and for long periods of time with great control, and little effort. Technique is not the same as musicality. Just because someone can play a scale really fast doesn't make him a musician, but if musicianship and technique are combined, they make a great player.
The word-skipping technique involves?
The word skipping technique involves focusing on the main idea of a passage.
