Suppose you have a near-point distance of 26 cm. The angular resolution of the eye is determined by diffraction (see the Rayleigh criterion) and is approximately 2 arcmin. (Note that 1°=60 arcmin.) What is the smallest object your bare eye can resolve?

Suppose you have a near-point distance of 26 cm. The angular resolution of the eye is determined by diffraction (see the Rayleigh criterion) and is approximately 1 arcmin. (Note that 1°=60 arcmin.) What is the smallest object your bare eye can resolve?
Constants Part A The maximum resolution of the eye depends on the diameter of the opening of the pupil (a diffraction effect) and the size of the light receptor cells (rods or cones) on the retina. The size of the retinal cells (about 5.0 am in diameter) limits the size of an object at the near point (25 em )of the eye to a height of about 50 pam. (To get a reasonable estimate without having to go through complicated...
Suppose that you have farsighted eye such that your near point is 95 cm. As a result you need a reading glass. What lens power (in D) must you wear so that a newspaper can be read at a distance of 25 cm? Assume the lens is very close to your eye.

Given: Assume the near point (of the eye) is 25 cm . The distance between eyepiece and objective lens in a certain compound microscope is l = 17.6 cm . The focal length of the eyepiece is fe = 2.57 cm , and that of the objective lens is fo = 0.3 cm . What is the overall magnification of the microscope? Caution: a negative quantity this is. Use the approximation l − fe ≈ l and object distance do...
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...
The near point of a patient's eye is 44.2 cm. (a) What should be the refractive power ℛ of a corrective lens prescribed to enable the patient to clearly see an object at 21.0 cm? ℛ = dpt (b) When using the new corrective glasses, the patient can see an object clearly at 24.4 cm but not at 21.0 cm. By how many diopters did the lens grinder miss the prescription? dpt
A diffraction- limited eye with a 6 mm pupil is looking at an approaching car whose headlights have a wavelength of 550 nm and are separated by 1.5 m. a) What is the minimum angular resolution of the eye? b) At what distance can you no longer resolve two distinct headlights?
