to determine the angle of minimum deviation. To find out the refractive index of various liquids using a Hollow Prism. INTRODUCTION: This project is of Investigatory Type. In this project‚ a hollow prism has been used to calculate the refractive index of various liquids. The hollow prism is filled with liquid and then the experiment

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

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 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

INDEX NUMBER Introduction Sebuah index menunjukkan perubahan relatif yang terjadi pada sebuah nilai dari satu periode ke periode yang lain. Kegunaan index‚ misalnya pada Consumer Price Index‚ adalah mengukur perubahan harga pada suatu kelompok besar dari barang-barang yang dibeli konsumen.

CPI (Consumer price index) A consumer price index (CPI) measures changes in the price level of consumer goods and services purchased by households. The CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically. GDP deflator In economics‚ the GDP deflator (implicit price deflator for GDP) is a measure of the level of prices of all new‚ domestically produced‚ final goods and services in an economy. GDP stands for gross

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

be honest I was kind of confused; it seemed like these tests were just like any other tests we had taken in school for math or reading but as I found out later in my school career‚ these tests were not like other tests and did not have the same purposes as a regular academic test used to measure our knowledge. The impetus for standardized testing started in the 19th century and has continued on until today‚ Standardized Testing has increased more and more as well as the misuse of test scores‚ increased
