Aim:- To investigate the effect of changing the temperature of glycerin on the index of refraction. In this experiment I will be using a simple method‚ which needs the following materials 40ml of glycerin in a beaker‚ protractor‚ a pencil‚ a laser‚ a paper to draw boundaries‚ circular plastic plates‚ hotplate‚ ruler and a digital thermometer. In this experiment 1 trial will be conducted for glycerin with 70 Celsius degrees ‚66‚62‚58‚ and another trial with 10 Celsius degrees. Scientific Background:-

faces the source of light. Automobile enthusiasts often call it a fish eye mirror while other physics texts refer to it as a diverging mirror. The term “diverging mirror” is based on this mirror’s behavior of making rays diverge upon reflection. So when you direct a beam of light on a convex mirror‚ the mirror will allow the initially parallel rays that make up the beam to diverge after striking the reflective surface. Since convex mirrors have wider fields of view than other

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Pre-literate societies had successfully transmitted values‚ traditions and skills to the succeeding generations. But alas!

Reflection (physics) From Wikipedia‚ the free encyclopedia The reflection of Mount Hood in Mirror Lake. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light‚ sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected

Refraction: Does light travel faster in water or air? A straight stick appears bent when partially immersed in water; the sun appears oval rather than round when it is about to set; a stream may appear to be much shallower than you know it to be. These are some of the effects caused by the refraction of light as it passes at an angle from one medium to another. Light refraction happens every day in almost every little thing‚ it is an optical illusion. For our science fair project my

I will reflect on an incident that occurred during my shift to develop positive attitude towards nursing informatics. In this reflection‚ I am going to use Gibbs (1988) Reflective cycle. This model is a recognized framework for my reflection. Gibbs (1988) consist of six stages to complete one cycle which is able to improve my nursing informatics and learning from the experience for better practice in future. The cycle starts with description of the situation‚ analysis of the feelings‚ evaluation

Geometrical Optics: Snell’s Law PHY101 Lab 12 Date: July 23rd‚ 2012 Objective: The purpose of this laboratory activity is to develop a set of experimental procedures that answer questions regarding Snell’s Law and the index of refraction. Ultimately‚ the experimental procedures you develop will allow the index of refraction to be found for water and cooking oil. 1. Explain how to experimentally determine the index of refraction of two substances. 2. Develop a set of experimental

Of course‚ we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface‚ incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a good example. You can see just how rough it is if you peer at it under a microscope. When light hits paper‚ the waves are reflected in all directions. This is what makes paper so incredibly useful -- you can read
