(a) A large optical telescope with an aperture of diameter 2.4 m is used to study the Moon. What is the size of the smallest feature on the Moon that this telescope can resolve using blue light which has a wavelength of λ = 400 nm?

(b) Calculate the size of the smallest object on Mars that this telescope can resolve. Assume Mars is at its closest distance 7.8 × 1010 m from the Earth. Ignore the effect of the Earth’s atmosphere on the resolution.

The resolution of a lens can be estimated by treating the lens as a circular aperture. The resolution is the smallest distance between two point sources that produce distinct images. This is similar to the resolution of a single slit, related to the distance from the middle of the central bright band to the firstorder dark band; however, the aperture is circular instead of a rectangular slit which introduces a scale factor. Suppose the Hubble Space Telescope, 2.4 m in...

The telescopes on some commercial surveillance satellites can resolve objects on the ground as small as 94 cm across (see Google Earth), and the telescopes on military surveillance satellites reportedly can resolve objects as small as 10 cm across. Assume first that object resolution is determined entirely by Rayleigh's criterion and is not degraded by turbulence in the atmosphere. Also assume that the satellites are at a typical altitude of 396 km and that the wavelength of visible light is...

32.5: The primary mirror of the Hubble Space Telescope is 2.4 m in diameter. Suppose it is most sensitive to light of wavelength of 820 nm.    a) What is the diffraction limited angular resolution of the Hubble Space Telescope?    b) If the HST were used to look at the surface of the Moon, what is the minimum distance between two distinguishable points? (The Moon orbits at a distance of 384000 km from the center of the Earth which...

a) The Mount Palomar telescope has an objective mirror with a 508 cm diameter. Determine its angular limit of resolution at a wavelength of 550 nm (in radiants and degrees). (Recall that you can resolve two objects only if the maxima of their images are separated by at least the radius of the first dark fringe of each image’s Airy disk). b) How far apart must two objects be on the surface of the Moon if they are to be...

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 500 km. The dunes are 1 m in diameter (horizontal size, as seen from above). The wavelength of instrument operation is 600 nm. The large-format detector is a CCD with 4096x4096 array of pixels, where each pixel is 20x20 microns in size. The scientist requires that...

very optical device has an angular resolution, the smallest angle over which it allows us to tell if two dots -- or two stars -- are distinct. If two stars have an angular separation less than the angular resolution, they appear as as a single object. This limited angular resolution can arise for a number of reasons: quality of the optics, blurring of the atmosphere and quantum mechanics. For example, from the ground on Earth, due to the blurring of...

I have heard the following statement many times: “The only manmade object on the surface of the Earth that is visible from outer space is the Great Wall of China”. Is this true??? In order to “see” the Wall, our eyes must be able to resolve both sides of the Wall. The maximum width of the Wall is 7.0 m. Let’s assume that you are looking down at the Wall from space from a very low-Earth orbit, an altitude of...

You joined the SQU science fiction club which is making an animation video about time travel to the early solar system when the moon was closer to Earth. Your task is to arrive at an accurate description of the orbital motion of the moon at the early solar system when it was at 0.80 the current distance from Earth. You summarized your task in the following questions that you are addressing in order:Hint: Remember the application of Kepler laws in...
