A reflecting telescope is used to observe two distant point sources that are 3.00 m apart with light of wavelength 600 nm. The telescope's mirror has a radius of 4.0 cm . What is the maximum distance in meters at which the two sources may be distinguished? Express your answer in meters to two significant figures.
here lemda = 600 nm R = 4cm D = 2R = 8 cm f = 3 m
as we know that
the maximum distance at which the two sources may be distinguished
Q = 1.22 lemda f / D
= 1.22 x 600 x 10-9 x 3 / 0.08

Please answer with work shown. Thank you! :) A reflecting telescope is used to observe two distant point sources that are 3.00 m apart with light of wavelength 600 nm. The telescope's mirror has a radius of 3.5 cm. What is the maximum distance in meters at which the two sources may be distinguished? Express your answer in meters to two significant figures.
Two stars are 4.0 × 1011 m apart and are equally distant from the earth. A telescope has an objective lens with a diameter of 1.86 m and just detects these stars as separate objects. Assume that light of wavelength 480 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.
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
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.
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...
If you don't solve this problem correctly in 3 tries, you can get a hint. Use the angular resolution for the Hubble Telescope to determine the smallest detail which it can observe on the moon, if the moon is 3.82 x 10 m away. Assume an average wavelength of 500 nm, and that the telescope's diameter is 2.40 m. The headlights of a car are 1.14 Vm apart. What is the maximum distance at which the eye can resolve these...
Two stars are 3.7 3 1011 m apart and are equally distant from the earth. A telescope has an objective lens with a diameter of 1.02 m and just detects these stars as separate objects. Assume that light of wave- length 550 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.
Part A Two point sources of light are separated by 6.0 cm . As viewed through a 10 μm diameter pinhole, what is the maximum distance from which they can be resolved if red light ( λ = 690 nm) is used? Express your answer using two significant figures. Part B If violet light ( λ = 420 nm ) is used? Express your answer using two significant figures.
Two lightbulbs are 1.0 m apart. From what distance can these lightbulbs be marginally resolved by a small telescope with a 4.0-cm -diameter objective lens? Assume that the lens is limited only by diffraction and 1 = 600 nm. Express your answer with the appropriate units.
Problem 2 a. Using the telescope on-board his spaceship, Captain Kirk barely manages to resolve two distant galaxies that are 0.3 arc-seconds apart (1 arc-second 1/3600 Degree). If he is imaging at 550 nm wavelength, what is the effective aperture (diameter) of the objective lens of the telescope? Assume that there are no geometrical aberrations. (5 points) b. Consider the following imaging setup with a transverse magnification Iml3, If we are to resolve the image of the two fixed point...
