Below are various procedures that you will conduct for this lab. The objective of this experiment was to analyze the laws of reflection and refraction. More about Reflection and Refraction Lab . Conclusion/Discussion With this experiment we begin the study of light and its interaction with various optical components. To do this, we needed to determine the index of refraction for different materials and to use the total internal reflection method. Not actually a UFO. The law of reflection states that the angle of reflection and angle of incidence are equal, with . The independant variable in this experiment was the strength of the solutions (75% Salt 25% Water etc.). Auxiliary Materials: The downloadable protractor listed at the above web page is provided to students for inclusion in the Data section of their lab notebook. Place the last pin several centimeters from the curved side of the box, so that it appears to line up with the other 2 pins as you look through the liquid. Refraction occurs when light enters a more or less optically dense medium, which therefore has a different refractive index (measure of the velocity light can travel at in the medium compared to in a vacuum in which it can travel at 2.9 x 108ms-1). In our case, water is the one which is more optically dense. index of refraction for the perspex is 1.50. Experiment 11 consisted of four . This causes the light's speed to increase or decrease . It. Reflection and Refraction (Names) (Institution Affiliation) (Date) Reflection Reflection refers to the change in course of the "wavefront" at a boundary between two . Reflection is defined as the reversal in direction of a particle stream or wave upon encountering a boundary. In this lab, the "laws" of reflection and refraction are to be studied by using the equivalence of these two ideas. (In other words, is there a peak in Graph 2? This is the measured resonance frequency. Refraction is described mathematically by Snell's law . If the index of refraction for water is n 1 = 1.3, will the critical angle for total internal reflection be greater than or smaller than the critical angle you recorded for glass? Dispersion is defined to . In this experiment, the. Reection from a plane mirror This is to say, we find the critical angle when the value of the incident theta is equal to 90 and thus sin(i) is equal to 1. Refraction occurs when light rays bend and change direction as they travel across the boundary into the second medium, causing a change in the light's velocity. Lab Preparation When light travelling through air encounters a different material, part of the light energy is reflected back into the air and part of it is transmitted into the glass, Pre-Lab Discussion Laser Safety Lasers in the classes IIIa and IIIb are capable of causing damage to the eye when a laser in one of these classes is directly exposed to a person's eye, or in some cases, when reflecting off of a smooth surface. Determine the path of the light before it strikes the mirror and after reflection from the mirror. Looking through the liquid in the box, align your eye so that you see the two pins on the other side of the box in line with each other. 2. This gave us a percent error of 3.3%. 2)The incident ray, the refracted ray and the normal to the surface, all lie in the sameplane. More about Reflection and Refraction Lab . Observations are accurate. At what frequency is the peak?) of the Law of Reflection and Snell's Law (Also known as the Law of Refraction). Class IIIb Lasers Lab Report 658 Words | 3 Pages. Using a ruler, find the centre of the flat side of a piece of Lucite. For refraction, Snell's Law will be tested. 13 Pages. use a ruler, or some form of straight edge and include these sketches in your lab report as figures to which you can refer in your conclusion, as necessary. The index of refraction is defined as the speed of light in vacuum. The resulting value of the refracted theta will then be equal to the critical angle. Materials Needed: pencil or straw, clear glass, water. Place the lenses near one end of the optical bench and the screen at the other end, as shown below. Procedure: The light source is placed on a blank sheet of paper and turned the wheel to select a single ray. Investigation 1.2 Angles of incidence and reflection a. These happens due to the density of two media. Refraction of Light Lab Answers Refraction of Light PART I This laboratory was designed to investigate the behaviour of light as it travels through a less dense into a denser medium. This change in direction of the transmitted light is refraction Section te Student Name Report on Laboratory Experiment "Reflection and Refraction of Light" Table I: Reflection of light Angle of incidence, 45 50 degrees 70 75 80 Angle of degrees Table II: Refraction of light Angle of degrees Angle of 10 20 30 40 50 60 70 80 refraction, degrees . Whenever a light strikes the surface of some material at an angle, part of the wave is reflected and part is transmitted (or absorbed). The reference line that is used is called a normal. Place a pencil (or straw) in a clear glass of water. Since light has the maximum speed in vacuum, the index of refraction for any material is always greater than 1. Rotate the trapezoid slowly and watch as the refracted rays get closer and closer to the outer surface of the trapezoid. The refractive index Aim: The aim of this experiment is to find the refractive index of a glass prism. . The first law of reflection = % states that when the incident ray hit a smooth plane surface, creating an angle called the incidence angle, it where: n = index of refraction will lie on the same plane as the normal line and its v = velocity of the medium reflected ray. The growth of the plants over time was the dependant variable (The dependant variable is the total growth). IV. Data section includes an organized documentation of observations for both parts of the lab (The Broken Pencil and the Marching Soldiers). This lab report gives an analysis of the study taken regarding the two behaviors, that is, refraction and dispersion of light. Optics Reflection And Refraction Lab Report Conclusion.
