Objective The objective of this experiment is to understand reflection and refraction and how they vary with different matters. At the end of this experiment‚ you will be able to: Determine index of refraction of various solutions Recognize the passage of refracted beams though different medium Understand the concept of Snell’s Law Understand how the speed of electromagnetic waves in different matters are related Determine the critical angle for total internal reflection Materials 550

The refractive index Aim: The aim of this experiment is to find the refractive index of a glass prism. In this experiment‚ the independent variable is the angle of incidence‚ and the dependent variable is the angle of refraction. Theory: Snell’s law relates the angle of incidence and refraction to the ratio of the velocity of the wave in the different media. The formula for Snell’s law is the following: Sin isinr = v1v2 = n Where i is the angle of incidence‚ r is the angle of refraction

Introduction: Stock index is very much important leading indicator which can be used for several purposes. It can be used as a benchmark to judge the performance of professional money managers. It can be used to facilitate the establishment and maintenance of several types of index fund and exchange traded fund (ETF). Securities analysts‚ portfolio managers‚ and academicians doing research use stock market indexes to examine the factors that influence aggregate security price movements and to compare

The Inaba text describes the phenomenon of "therapeutic index." Addiction to barbiturates can be critical in terms of lethality as measured by the therapeutic index. Describe how this phenomenon might lead to an accidental overdose. Why is this factor more critical with barbiturates than with other classes of depressant drugs? Barbiturates are nonselective central nervous system (CNS) depressants‚ capable of producing all degrees of depression from mild sedation and hypnosis to general anesthesia

wavelength of light. Because the velocity of light in air is always greater than that through a liquid‚ the refractive index is a number greater than 1; for example‚ hexane n20D 1.3751. The superscript 20 indicates that the measurement was made at 20 oC‚ and the subscript D refers to the yellow D-line of a sodium vapor lamp‚ light with a wavelength of 589 nm. The measurement is made with a refractometer using a few drops of liquid. Compensation is made within the instrument for the fact that white

The index of dissimilarity The index of dissimilarity measures the evenness of two racial groups distributed across an area in relation to a larger area. The scale ranges from zero‚ complete integration‚ to one‚ complete segregation. The index can be used with the analysis of racial segregation in trends dealing with socioeconomic class‚ immigration‚ nativity‚ and residence. Generally‚ without immigration‚ the dissimilarity index between two races decreases as time goes on. This trend is most noticeable

Race and racism have several influences of the shaping and image of both the NHL and the NBA. The NHL is viewed as a white-race dominant league and the NBA is viewed as a black-race dominant league. It is often perceived for this reason that the NHL is the more professional of the two leagues and that the athletes in the NBA are less professional due to their choice of clothing apparel most specifically. The NBA and NHL are both known to discriminate against the black athletes and it is believed
