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.

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.

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?

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?...

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...

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...

When laser light of wavelength 632.8 nm passes through a diffraction grating, the first bright spots occur at ± 17.0 ∘ from the central maximum. How many additional pairs of bright spots are there beyond the first bright spots? A converging lens 6.90 cm in diameter has a focal length of 310 mm If the resolution is diffraction limited, how far away can an object be if points on it transversely 4.00 mm apart are to be resolved (according to...
