# Reflection and refraction lab

Objective in this set of experiments, reflection and refraction of light will be studied for reflection, exper- iments will be done to determine if the angle of reflection is equal to the angle of incidence for a beam of light incident on a flat surface for refraction, snell's law will be tested equipment list laser pointer, a lab-jack,. Objectives: to test the laws of reflection and refraction to measure the indices of refraction for water and glass to find the position of the image produc. Reflection & refraction lori andersen one day in my classroom“my students were amazed by examples of colorful fiber optics but didn't understand how the light goes from one end to the other even when bent after testing various angles of laser light through water and air up to 40 degrees, most. This lab explores the physics of refraction and lenses snell's law was used to measure the index of refraction for water using measurements of incident and refracted angles the phenomenon of total internal reflection at the water-air interface was also observed it was shown that concave lenses can focus light and also. Conduct dozens of light science experiments and light science demonstrations with the elementary reflection and refraction kit collect and analyze data, make observations and draw conclusions while students explore and experiment with the fundamentals of light this robust and flexible hands-on light science kit.

Lab handout lab 20 reflection and refraction how can you predict where a ray of light will go when it comes in contact with different types of transparent materials introduction our understanding of the nature of light and how it behaves has changed a great deal over the centuries the first real explanations for. Questions procedures a, b, c: bouncing light off mirrors according to the law of reflection, the incident angle and the reflection angle must be the same discuss: how well does your experiment show this does it matter whether the reflective surface is flat or curved why the results were very good, all angles. Explore bending of light between two media with different indices of refraction see how changing from air to water to glass changes the bending angle play with prisms of different shapes and make rainbows.

Margaret wettergreen phy 2049l 03/20/2014 lab #9: reflection, refraction and total internal reflection purpose: the purpose of this lab was to study some of the basic laws of optics we did this by testing the laws of reflection, refraction ( snell's law), and total internal reflection by conducting four experiments using a. When light crosses from one material to another, its straight line path will bend by an amount determined by the speed of light in both materials this “bending” of light is called refraction the interface between two materials also causes reflection of light see figure 1 the law of reflection states that the.

The critical angle refers to an angle of incidence that produces a corresponding emerging ray that has an angle of refraction of 90° it is largest possible angle of incidence that doesn't result in total internal reflection in this activity, it was estimated to be 43° conclusion by doing this experiment it can be proved that there. This lab follows general procedures for studying reflection and refraction using a mirror, laser pointer and protractor.

Preparation review the laws of reflection and refraction and snell's law understand the concept of total internal reflection review the geometry of a prism know the lensmaker's equation goals of the experiment to study and observe the laws of reflection and refraction to understand and practice optical ray tracing. You'll find light science experiments about both light refraction and light reflection in this science roundup light science for kids: science activities and experiments about light refraction and light reflection because we have water refraction science experiment from what do we do all day how to. Reflection and refraction lab purpose: the purpose of this lab is to learn about the behavior of light when it encounters a boundary separating two different materials intro definition: refraction refers to the change in direction of light that occurs when light goes from one material (like air) into a second material (like water.

• Verify the laws of refraction and reflection measure the wavelength of light, using the data from the lab/problem solving method at the end of this unit the student will demonstrate the ability to: given a transverse wave diagram and the time required for the completion of one cycle determine frequency, period, wavelength,.

Reflection, refraction and lenses (geometric optics) geometrical optics theory (pp 1-3) most of the observations in this experiment are made within the framework of geometrical optics, neglecting interference and diffraction effects in this formulation, the direction of propagation of light waves. This lesson examines what reflection and refraction are and demonstrates how they work using experimentation you'll be provided with step-by-step. Experiment #1: reflection, refraction, and dispersion purpose: to study reflection and refraction of light at plane and curved surfaces, as well as the phenomenon of dispersion equipment: ray box with slits optical accessories ( flat mirror, 3-sided chrome mirror, plastic biconvex lens, plastic plane-parallel slab, glass 60.
