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...

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...

(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...
