OBJECTIVE The objective of this experiment is to study refraction and reflection and also to use Snell’s law correctly to determine the optical properties and indices of refraction for a prism. DATA All data is included in an excel spreadsheet‚ attached to this write-up. Some uncertainties that see probable in the case of general human error are the basic visualization of the location of the pin‚ the measuring of the angles with a protractor‚ the possibly imprecise way to draw the reflected

Mary Fenning Lab 12 Reflection‚ Refraction‚ & Lenses Introduction The purpose of is lab is to observe ray models of light and how light refracts and reflects through a straight line and Snell’s Law. Procedures Setup and materials: Part IV: Procedure: Using the slit plate observe the rays on the viewing screen set Rotate the slit plate until the slits are horizontal. Record what image looks like at the different angles Trace the rays onto a white piece of paper and extend the lines
Premium Refraction Light Optics
The refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water

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

of the Law of Reflection and Snell’s Law (Also known as the Law of Refraction). Reflection is defined as the reversal in direction of a particle stream or wave upon encountering a boundary. The law of reflection states that the angle of reflection and angle of incidence are equal‚ with each angle being measured from the normal to the boundary: Refraction is defined as the bending of light that takes place at a boundary between two materials having different indices of refraction due to a change

Light Reflection and Refraction Pre-Lab using PhET I) Introduction: When a light ray strikes a smooth interface separating two transparent materials (like air‚ glass‚ or water)‚ the wave is partly reflected and partly refracted (or transmitted) into the second material. For an example of this‚ imagine you are outside looking at a restaurant window. You can probably see both the inside of the restaurant (from the refracted light) and some of the street behind you (from the reflected light). Similarly

Lab reflection: Light reacts to different density in different ways. An example when it goes through a low density medium to a high density medium the angle of refraction decreases. With all the test done the angles of incident and reflection stayed the same. This is because with light what angle it approaches at is the angle the light will reflect back at. Also the angle of refraction depended on what the angle of incident and refraction were‚refraction is a dependent variable being the reason

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

Refraction Refraction refers to the bending of the transmitted light at the interface between two transparent materials. The angle of refraction depends on the angle of incidence and the relative speeds of the light in the two different media and can be found from the relationship [pic] From this equation we see that the direction in which the light is bent depends on whether it is going from a slower to a faster medium or vice versa. Index of refraction The index of refraction of
