Introduction: Refraction‚ is the bending of a light ray when it pass from one medium to another. It occurred because the speed of the light travelled in different medium was inconsistent (Encyclopædia Britannica‚ 2016). Referring to the following diagram‚ i is the angle of incidence of light (assumed in a vacuum)‚ and the line that is perpendicular to the surface of the medium. r is the angle of refraction which indicate the angle between the line of normal and the light ray in the medium (Encyclopædia

Introductions: The bench work and fitting play a important role in every engineering workshop to complete and finish the job to desired accuracy. The work carried out by hand at the bench is called bench work. Whereas fitting is the assembling of parts together by filling‚ chipping‚ sawing‚ scraping and tapping etc. Fitting shop tools: The tools which are used in fitting lab are called fitting shop tools. These can be classified into the following groups according to their function they performed. 1

An Introduction to Titration: Standardization of HCl and NaOH Lab Report Introduction: It is important to standardize solutions in order to have the accurate amount of concentration known. A standard solution can be prepared in either of two ways: A primary standard is carefully weighed‚ dissolved‚ and diluted accurately to a known volume. Its concentration can be calculated from this data. A solution is made to an approximate concentration and then standardized by titrating an accurately weighed

How the change between physical and semantic processing affects the accuracy of word recall Psychology group 11-1 Siobhan Mackenzie Introduction The level of processing approach‚ founded by Craik and Lockhart‚ 1972‚ is a theory of memory in which the accuracy of recall is directly affected by the level of analysis of any given material. The level of processing model of memory was put forward to try and overcome criticism aimed at an earlier research multi store model. Shallower processing has

By repeating each test for the different colours of light three times‚ it was possible to calculate the mean of the results‚ as well as determine the precision of the results and determine outlying figures. Conducting multiple tests also allows for conclusions regarding the precision and accuracy of the experiment to be made more confidently and easily. Another strong point in the method was lining the boxes containing the samples with aluminium foil to create a reflective

INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter

The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye
