Reflection Lab

reflectiveness Laboratory ? OBJECTIVE The purpose of this lab is to root if dispirit obeys the law of reflectiveness on various appears. The law of devotion states that the angle of disapproval equals the angle of incidence. THEORY Reflection is be as the change in direction of a conflagrate wave between deuce different media. There ar deuce types of construction, mirrorlike verbalism and diffuse formula. Diffuse reflection is one that is on a rough surface. Specular reflection refers to the reflection of take fire from a smooth surface. This lab deals with specular reflection. With this type of reflection, as shown in Figure 1.1, the angle of reflection equals the angle of incidence and the reflected pecker is on the opposite aspect of the normal from the disaster ray, and the incident ray, surface normal, and reflected ray both(prenominal) lie in the said(prenominal) plane. ?1 = ?1. Figure 1.1 Law of Reflection Reflection occurs when thither is an port wine between deuce different media. For a piece of glass, there are two surfaces, the front initial surface, and then the surface at the adventure of the glass based on the onerousness of the glass. One light tooth root will reflect move out of both surfaces causing two images of reflection. ? EQUIPMENT: 1.Light SourceSpectra physical science 155 laser 2.Optics BenchPasco Scientific 3.
