Hint: For light to stay within the optical fibre‚ it must be incident on the air-glass interface at angle greater than the critical angle. Use Snell’s law n1sin 1=n2 sin 2 with 2 = 90˚. Solution: 1.50sin 2=1.31 b) Determine the maximum angle for which the light rays

Eutrophication Introduction Europhication (the over enrichment of aquatic ecosystems with nutrients leading to algal blooms and anoxic events) is a persistent condition of surface waters and a widespread environmental problem (Carpenter‚ 2005). The main cause is excessive loading into the system of phosphorus and nitrogen‚ resulting in high algal biomass‚ dominance by cyanobacteria‚ and loss of macrophytes (Dixit‚ 2005). When the nutrient concentrations rise to extremely high levels‚ eutrophication

Optical Distortion‚ Inc. case Daniel Garrison‚ the president and CEO of Optical Distortion‚ is thinking about to bring the new and only product‚ a contact lens for chickens‚ to the markets. Working with Ronald Olson‚ the marketing vice president‚ Garrison is currently developing a marketing plan for ODI’s new product. ODI is planning to introduce these contact lenses to at least one region at the beginning‚ hoping to reach national distribution in a couple of years. There are three different sizes

SITUATION ANALYSIS: Optical Distortion Inc.(ODI) markets lenses that distort the vision of chickens. These lenses are used instead of debeaking. Lensed chickens are more likely to survive from cannibalism among the chickens. The lenses are also supposed to reduce the amount of feed per chicken per day than that for debeaked chickens. Using lenses do not lead to any trauma among chickens and therefore do not affect their egg laying capacity. The objective of the case is to present a financial

What Causes Optical Illusions? Optical illusions are how the eye sees the illusion. Most people now believe that seeing optical illusions has to do with perspective‚ or the way you look at something. The concept of optical illusion was first used by the Greeks. They built their temples so that the roof was slanted. This gave the illusion that the temple was actually standing straight. We get used to how things are supposed to be‚ and sometimes our brain gets the wrong message. Our brain puts

transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic waves that is modulated to carry information. First developed in the 1970s‚ fiber-optic communication system have revolutionized the telecommunication industry and have played a major role in the advent of the information over age. Because of its advantages over electrical transmission‚ optical fibers have largely replaced copper wire communications in core networks in the

In this assignment‚ we are assign to construct a 2 button type Ac motor control system. The 2 type button means that there are only 2 buttons which is the stop button and the forward button. The successful build the whole system‚ a few component are very critical in this system. Circuit breaker First is the circuit breaker. Circuit breaker is a switch which is designed to prevent damaging the circuit when there is over load or short circuit. But the circuit breaker works differently compare
