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?

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 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.

2) (Diffraction limit of human eye) (Adapted from a problem by Prof. Walter Smith.) Let's see how the resolution limit for the human eye due to diffraction from a circular aperture (the pupil) compares to that required to see things on computer screens and high-def TVs. Assume that the wavelength of light is 550 nm on average, and that the pupil of the eye has a diameter of 4.00 mm. a) How does the angle subtended by a single picture...

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...
