Physics-131: Lab 3 Prof. Anchordoqui Laws of reflection and refraction I. This was due to the optical densities of two media. In refraction we will learn that the angle of the ray when transmitted through the material changes and depends on the speed of light in the two materials. Compared to the angle of incidence, the angle of refraction was smaller. Because the velocity of light in air is always greater than that through a liquid‚ the refractive index is a number greater than 1; for example‚ hexane n20D 1.3751. Whenever a light strikes the surface of some material at an angle, part of the wave is reflected and part is transmitted (or absorbed). I need answers for the attached lab questions, calculations, discussion part, and the graphs.. Choose the protractor and set the laser to an angle of incidence, θ 1, at 30°. 2)The incident ray, the refracted ray and the normal to the surface, all lie in the sameplane. ranked the liquids from most refraction to least refraction, then the lab and discussion should just confirm their prediction. θc=sin− 1. Index of Refraction Lab. SNC 2DI – REFRACTION OF LIGHT (Snell’s Law) LAB Purpose: To observe the refraction of light as it passes from air into Lucite (plexiglass) and to calculate the index of refraction for Lucite. See Figure 1. In this lab, the "laws" of reflection and refraction are to be studied by using the equivalence of these two ideas. The purpose of this experiment was to test the validity of the Law of Reflection and Snell’s Law (Also known as the Law of Refraction). Fresnel Reflection 1. A fun, multi-day, inquiry-based experiment that will help students see how different colors absorb and reflect light. 20. Purpose: When light travels through different mediums, it is being refracted. Thus θ i = θ r. Law of refraction. 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. by. Generally, the incident ray is partially reflected and refracted. If anything, the tasks that are issued keep getting complicated, the deadlines become stricter, and the instructions get confusing. 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. Reflection and Refraction Lab Page 3 Seeing reflection and refraction at the same time Both refraction and reflection often occur when light hits a boundary between materials such as the boundary between glass and air. The angle of incidence in the more refractive medium must be larger than the critical angle. See Figure 1. The index of refraction would be measured using the following methods: Snell’s law minimum deviation from a prism total internal reflection Brewster’s angle apparent depth Theory: When a monochromatic light ray (single color/wavelength) passes from air to a transparent medium, it is refracted from its original direction and can be described using Snell’s law: sin 2 = = sin 1 where … Lab Handout Lab 20.

As one can notice, this test of reflection and refraction in glass was a success given the precise values obtained by the index of refraction. The Snell’s law of refraction states that n1sin θ1 is equal to n2sin θ2. Conclusion/Discussion Updated: 11/03/2021 Create an … Using a ruler, find the centre of the flat side of a piece of Lucite. The Refraction of Light Waves: The bending of light is known as Refraction. Amanda has taught high school science for over 10 years. 1. The “n” refers to the index of refraction that describes the optical density of the material. The reflected ray was also in the same plane where the incident ray was. For refraction, Snell’s Law will be tested. When light is shone off a spherical mirror, it will converge at a focal point. Checkpoint WhatisSnell’sLaw? When the phrase "ray of light" is used, it often means the same as "line of sight". In the first part of this lab, we will investigate the basic principles of ray optics, Snell's law and the Law of Reflection. To explore the rules that predict reflection and re-fraction in optical materials. 2. For re ection, exper-iments will be done to determine if the angle of re ection is equal to the angle of incidence for a beam of light incident on a at surface.
