Lab Exercise 5: Reflection and Refraction - 00067672.
Reflection and Refraction s) Affiliation) Reflection Reflection refers to the change in of the “wavefront” at a boundary between two different media whereby the wavefront gets back to the same medium in which it emanated. Regularly, light, water and sound waves undergo reflection (Anonymous, 2010).The nature of reflection depends on the nature of the surface in which the wave comes into.
The following is the type of diagram that we draw for reflection; If a surface is a rough surface, the equation so holds true except the surface will have jagged edges in all directions, which means the angle of incidence varies and thus the angle of reflection will also vary. Refraction.
When light travels from one medium to another (like air to glass, or glass to water), it does three things. Some of it bounces off, some of it goes through, and the rest of it is absorbed. In this chapter, we will explore the first two. We will explore what rules govern them, their technical names and then apply these rules to study the beautiful world of curved mirrors and lenses.
PHY 124 - Optics: Reflection, Refraction and Images. There are two parts to this lab that can be done in either order. In Part I you will study the Laws of Reflection and Refraction, measure the index of refraction of glass and observe dispersion. In Part II you investigate images produced by lenses.
The pack from my new 5th Grade Science Test Prep product line has 20 multiple choice task cards that ask students to show their understanding of the reflection and refraction of light These rigorous questions require students to analyze and interpret information to construct reasonable explanations.
Reflection and Refraction Equipment Acrylic block set, plane-concave-convex universal mirror, cork board, cork board stand, pins, flashlight, protractor, ruler, mirror worksheet, rectangular block worksheet, equilateral prism worksheet, converging lens worksheet. Preparation Review the laws of reflection and refraction and Snell's law.
LAB: Reflection and refraction. Why do you use a laser in this lab rather than a light bulb? If you wanted to use a light bulb, what would you have to do to the light bulb? Procedure: Part I: Reflections. Place a blank piece of paper on your table. Place a mirror on the paper. You may need to support the mirror with clothespins or paperclips.
