The objective lens of a certain refracting telescope has a diameter of 59.0 cm. The telescope...
A spy satellite uses a telescope with a 1.5-m-diameter mirror. It orbits the earth at a height of 220 km. What minimum spacing must there be between two objects on the earth's surface if they are to be resolved as distinct objects by this telescope? Assume the telescope's resolution is limited only by diffraction and that it records 500 nm light.
Name 1. A refracting telescope is built with a 44.0 cm diameter objective lens that has a 1.85 m focal length It is used with an eyepiece with an angular magnification of 14.0. (a) (5 pts) What is the local length of the eyepiece? (b) (5 pts) what is the angular magnification of the telescope? (c) (5 pts) What is the distance between the objective lens and the eyeplece? 2. (5 pts) Consider a microscope with a 21.6 em tube...
A refracting telescope is used to view the Moon (diameter 3480 km, distance from Earth 385,000 km). The focal lengths of the objective and eyepiece are +2.45 m and +16.1 cm, respectively. (a) What should be the distance between the lenses? m (b) What is the diameter of the image produced by the objective? cm (c) What is the angular magnification?
The Yerkes refracting telescope has a 1 m diameter objective lens of focal length 20 m. Assume it is used with an eyepiece of focal length 2.31 cm. Find the angular magnification of the planet Mars as seen through this telescope.
Constants Part A The resolution of a telescope is ultimately limited by the diameter of its objective lens or mirror. A typical amateur astronomer's telescope may have a 7.0 in. -diameter mirror What is the minimum angular separation (in arc seconds) of two stars that can be resolved with a 7.0 in. scope? (Take ? to be at the center of the visible spectrum, about 550 nm, and note that 1 arc sec 1/3600 ) Express your answer using two...
The Hubble Space Telescope has a mirror diameter of 2.4 m. Suppose the telescope is used to photograph stars near the center of our galaxy, 30,000 light years away, using red light with a wavelength of 720 nm . A) What's the distance (in km) between two stars that are marginally resolved? The resolution of a reflecting telescope is calculated exactly the same as for a refracting telescope. B) For comparison, what is this distance as a multiple of the...
the hubble space telescope has an objective diameter of 2.4 m. suppose it is viewing the mars from a distance of 80 million km away. estimate the minimum size of an object on mars (in km) that can be distinguished by the hubble when using a wavelength of 490 nm
The primary mirror on a telescope that orbits 600 km above Earth has a diameter of 2.4 m. a) Calculate the minimum angular separation that it might resolve for visible light. b) Assume that the telescope is viewing Earth’s surface. What is the separation of the most closely spaced objects that it might resole?
A converging lens with a diameter of 27.0 cm forms an image of a satellite passing overhead. The satellite has two green lights (wavelength 500 nm) spaced 1.40 m apart. If the lights can just be resolved according to the Rayleigh criterion, what is the altitude of the satellite?
What is the magnification of a telescope which has an objective lens of focal length 2.50 m and a diameter of 1.00 m, and an eyepiece of focal length 4.50 cm? What is the angular resolution of this telescope for visible light (wavelength = 550 nm)? What is the length of the telescope?
