How many times more light does a 16-inch diameter telescope mirror gather than your 2-inch telescope?
1. If you had a telescope that had a mirror 10 times the diameter of the human eye, how much more light would it collect? 2. Give two reasons why putting telescopes into space allows us to see things we would not be able to see from the ground.
The Keck telescope has a 10 m diameter mirror, and the human eye has about a 4 mm radius. How much more light can it collect with respect to the Human eye? 10 times About 1.5 million times About 6.25 million times About 1250 times
3) (10 pts) The Thirty Metre Telescope (TMT) is a 30m diameter telescope to be built on Mauna Kean in Hawaii. The Hubble Space Telescope is a 2.4m diameter telescope in orbit around the Earth. a) (2.5 pts) What are the angular resolutions of both telescopes when observing in "visible" light (1 = 550 nm)? How many times better or worse is the HST compared to the TMT? b) (2.5 pts) What are the angular resolutions of both telescopes when...
The telescope at Mount Palomar has an objective mirror that has a diameter of 508 cm. 1) What is the angular limit of resolution for 810-nm light in radians? (Express your answer to two significant figures.) x10-6 rad Submit 2) What is the angular limit of resolution for 810-nm light in degrees? (Express your answer to two significant figures.) x10-6 degrees Submit +
Assignment: Telescope Comparison Students will research three different telescope companies online and then complete the following for each telescope selected. Research one relatively inexpensive telescope (less than $750), one more expensive telescope (more than $1,000), and a third telescope of your choosing. The third telescope of your choosing cannot be a repeat of previous two studied. Please refer to Module 5, Telescopes & Observing, for details on telescope design. Websites researched Company #1: website address Company #2: website address Company...
A 6 ft diameter water wheel is placed on a 2 inch diameter shaft to generate electricity in a river. With one rotation of the water wheel how far - or how many times does the shaft turn?
Suppose you were to look at a star in the sky with your naked eye. The star's light enters your eye's pupil, which has a diameter of 0.6 cm. Now suppose you look at the same star through the Carleton observatory 14-inch (35.6 cm) diameter telescope. How many times larger is the light gathering power of the telescope compared to that of your naked eye?
Deep in the physics and astronomy basement storeroom, you find a very large concave spherical mirror from an old telescope. The mirror is 2 m across, and has a radius of curvature of 14.0 m. Because this is just a small piece of such a large sphere, the angle of incidence for on-axis rays will always be below 5°, minimizing spherical aberration You try out the mirror for use as a full-length wall mirror. If you look at yourself in...
