Assume the range of pupil variation during adaptation of a normal eye is from 2.0 to 7.1 mm. What is the corresponding range of distances over which it can detect the separation of objects 5 cm apart? Assume an average wavelength of 550nm.

1. The headlights on an automobile are 125 cm apart. At what distance will the lights appear to be just resolvable to a person whose nocturnal pupils are 4.5 mm in 2. Assume the range of pupil variation during adaptation of a normal eye is from 2.0 to 7.1 mm. What is the corresponding range of distances over which it can detect 3. Two stars make an angle of 1 x 10-3 radians at the eye of an observer. A...
An inkjet printer uses tiny dots of red, green, and blue ink to produce an image. Assume that the dot separation on the printed page is the same for all colors. At normal viewing distances, the eye does not resolve the individual dots, regardless of color, so that the image has a normal look. The wavelengths for red, green, and blue are λred = 660 nm, λgreen = 550 nm, and λblue = 470 nm. The diameter of the pupil...
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...
BACK NEXT Chapter 27, Problem 37 GO A hunter who is a bit of a braggart claims that from a distance of 2.0 kom he can selectively shoot either of two squirrels who are sitting 8.7 centimeters apart on the same branch of a tree. What's more, he daims that he can do this without the aid of a telescopic sight on his nine. (a) Determine the diameter of the pupils of his eyes that would be required for him...
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...
Sound of frequency 2.0 kHz falls at normal incidence on a high wall in which there is a vertical gap that is 30 cm wide. A man is walking parallel to the wall, on the other side from the source of sound, at a perpendicular distance of 20 m from the wall. Assuming a speed of sound of 340 m/s, over what range of distance would he hear an intensity of sound: (a) more than 50% of the maximum? (b)...
A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...
Production Line Simulation Random variation is an important part of most processes in operations and supply chain management. For example, customer demand, supplier lead time, answering a customer inquiry, or processing a batch of material at a machining center all vary from customer to customer, delivery to delivery, and batch to batch. As the chapter notes, simulation allows us to model randomness. Although most large-scale simulations are done on computers using random numbers, there are other ways to generate random...
Note: This test contains ten questions from chapter 19 to chapter 27. For full credit, you should show all the steps of your numerical answers. No credit would be earned for just circling the right answers. Chapter 19 - Electric Potential and Electric Potential Energy 1. Two point charges are of + 7 uC and - 4 C are held at the corners of a rectangle as shown. The lengths of the sides of rectangle are 0.15 m, and 0.05...
(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
