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)
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...
Question 1: [20 Points] a) The primary mirror of the orbiting Hubble Space Telescope has a diameter of 2.50 m. Being in orbit, this telescope avoids the degrading effects of atmospheric distortion on its resolution. The Hubble Space Telescope is observing light source coming from a very far away galaxy as shown in the figure above. The scientists are debating whether the light being observed is coming from a single light source or two different light sources. You as a...
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?
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...
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?
The Hubble Space Telescope has a diameter of 2.4 m. 1) What is the angular limit of resolution due to diffraction when a wavelength of 990 nm is viewed? (Express your answer to two significant figures.)

Find the minimum angular separation resolvable with 625 nm laser light passing through a circular aperture of diameter 2.1 cm . 3. The interference pattern from two slits separated by 0.35 mm has bright fringes with angular spacing 0.073 ∘. **express in nm**
A telescope with aperture diameter 1.0 m is used to observe a globular star cluster. What is the best resolution possible for this telescope? That is, what is the minimum angular separation needed to distinguish two objects? a. 0.732 radians b. 0.6 degrees c. 0.49 radians d. 36.9 degrees
A scientist requires the construction of a diffraction-limited telescope to image small dunes on Mars. The telescope will be mounted on a spacecraft instrument platform. The spacecraft will orbit Mars at an altitude of 400 km. The dunes are 2 m in diameter (horizontal size, as seen from above). The wavelength of instrument operation is 500 nm. The large-format detector is a CCD with 4096x4096 array of pixels, where each pixel is 30x30 microns in size. The scientist requires that...
