The two headlights of an approaching automobile are 1.4 m apart. At what (a) angular separation and (b) maximum distance will the eye resolve them? Assume that the pupil diameter is 5.0 mm, and use a wavelength of 524 nm for the light. Also assume that diffraction effects alone limit the resolution so that Rayleigh's criterion can be applied, in meters.

The two headlights of an approaching automobile are 1.3 m apart. At what (a) angular separation and (b) maximum distance will the eye resolve them? Assume that the pupil diameter is 5.0 mm, and use a wavelength of 560 nm for the light. Also assume that diffraction effects alone limit the resolution so that Rayleigh's criterion can be applied, in meters.

Diffraction Limit: How far away can a human eye distinguish two car headlights 2.0m apart? Consider only diffraction effects and assume an eye pupil diameter of 6 mm and a wavelength of 560 nm. What is the minimum angular separation an eye could resolve when viewing two stars, considering only diffraction effects? In reality, the minimum angular separation is about 1' of arc. Why is it not equal to your answer in part b)?

The limit to the eye's acuity is actually related to diffraction by the pupil. (a) What is the angle (in rad) between two just-resolvable points of light for a 3.23 mm diameter pupil, assuming an average wavelength of 565 nm? rad (b) Take your result to be the practical limit for the eye. What is the greatest possible distance (in km) a car can be from you if you can resolve its two headlights, given they are 1.45 m apart?...

The photosensitive cells (rods and cones) in the retina are most densely packed in the fovea - the part of the retina used to see straight ahead. In the fovea, the cells are all cones spaced about 1 pm apart. Would our vision have much better resolution If they were closer together? To answer this question, assume two light sources are just far enough apart to be resolvable according to Rayleigh?s criterion. Assume an average pupil diameter of 5.00 mm...
