Homework Answers
As the formula is given for diffraction limit =
25× 10^4 × (wavelength/ diameter)
= 25 × 10^(4) × 640 ×10^ (-9) /9 × 10^(-2)
= 1 . 78 arcse

The diffraction limit, the smallest angle in degrees that can be resolved, is 250,000 arcsec × (wavelength/diameter of telescope). Humans have two eyes separated by about 8.5 cm and a marvelous computer between their ears. If this optical interferometer is just as good as one eyeball with a diameter as large as the separation of two regular eyeballs, what is the diffraction limit in arcsec of human vision for visible light at 599 nm?

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...

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...

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)?

What is the smallest possible feature size that can be resolved by using a 193-nm optical source and the highest possible NA that can be obtained by a lens when exposing the image in air? Note that NA can be determined by the equation NA = n∙sin(θ) where n is the index of refraction of the medium in which the lens is working (air in this instance) and θ is the maximal half-angle of the cone of light that can...
