You plan to buy a telescope to allow you to see Jupiter’s Great Red Spot (GRS)? What is the smallest telescope aperture that will allow to do so (assume that the GRS can fit 3 Earth-size planets)?
Suppose you can just barely see a twelfth-magnitude star through an amateur’s 6-inch diameter telescope. What is the magnitude of the dimmest star you can see through a 60-inch diameter telescope?
A telescope can be used to enlarge the diameter of a laser beam and limit diffraction spreading. The laser beam is sent through the telescope in opposite the normal direction and can then be projected onto a satellite or the Moon. If this is done with the Otto Struve telescope, producing a 2.102.10 m diameter beam of 613613 nm light, what is the minimum angular spread of the beam? minimum angular spread: Neglecting atmospheric effects, what is the size of...
1. What is the minimum telescope aperture needed to resolve an object whose angular diameter is 0.38 arc seconds, observed at 540 nm wavelength? Note: 1arcsec=(1/3600)∘. **express in cm 2. 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**
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...
If the angular magnification of an astronomical telescope is 28 and the diameter of the objective is 67 mm, what is the minimum diameter of the eyepiece required to collect all the light entering the objective from a distant point source located on the telescope axis?
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 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...
Pls if you could help me and show the working that would be
great.
