The Keck Telescope has a diameter of 10.0 m. When it is looking at Mars, 7.38•1010...
The Hubble Space Telescope (still operational) has a mirror with a diameter of 2.4 m. What is the maximum resolution of Hubble when observing Mars at closest approach (typically 7.5 x 1010 m away)? Since Mars is mostly red, assume the light is reddish, with a wavelength of 630 nm. Could Hubble resolve the Endeavor crater (diameter 22 km) on Mars? 1. 2. Calculate the angle of incidence at which light reflecting off of crown glass (with an index of...
A telescope is used to observe two objects that are 10 km away from the telescope, and these two objects are 0.12m apart from each other. The wavelength of the light used for observation is 600 nm. Calculate the diameter of the objective lens of the telescope if it can just resolve the two objects. 0.12 m 10 km
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
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 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 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?
Problem 5 (18 points) The Hubble Space Telescope has an aperture of 2.4 m and focuses visible light (380- 750 nm). The Arecibo radio telescope in Puerto Rico is 305 m (1000 ft) in diameter and focuses radio waves of wavelength 75 cm. Under optical viewing conditions, what is the smallest crater that each of these telescopes could resolve on our moon? Earth-Moon distance = 3.8 × 108 m. a)
When laser light of wavelength 632.8 nm passes through a diffraction grating, the first bright spots occur at ± 17.0 ∘ from the central maximum. How many additional pairs of bright spots are there beyond the first bright spots? A converging lens 6.90 cm in diameter has a focal length of 310 mm If the resolution is diffraction limited, how far away can an object be if points on it transversely 4.00 mm apart are to be resolved (according to...
You are looking down at the earth from inside a jetliner flying at an altitude of 9500 m. The pupil of your eye has a diameter of 2.00 mm. Determine how far apart two cars must be on the ground if you are to have any hope of distinguishing between them with the following lighting. (a) red light (wavelength = 665 nm in vacuum) (b) violet light (wavelength = 405 nm in vacuum)
Two stars are 5.3 × 1011 m apart and are equally distant from the earth. A telescope has an objective lens with a diameter of 1.08 m and just detects these stars as separate objects. Assume that light of wavelength 490 nm is being observed. Also, assume that diffraction effects, rather than atmospheric turbulence, limit the resolving power of the telescope. Find the maximum distance that these stars could be from the earth.
