# snell's law experiment

Using the principles of refraction and Snell's law, experimentally determine the index of refraction of a transparent medium. All these phenomena can be explained using the concept of refraction and an experimentally validated equation known as Snell's Law. In this lesson we are going to look at a derivation of Snell's Law based on the Principle of Least Time. Now let us prove Snell's law of refraction through a simple experiment: Diagram of the experimental set-up: (Image to be added soon) Steps: Put a rectangular slab of glass on a piece of paper, preferably white in colour. (30%)PART 1: SNELL’S LAW OF REFRACTION Goal Determine the index of refraction of a prism. A ray of light beginning in the top medium travels through the interface into the bottom medium. In the diagram shown above, two mediums are juxtapositioned one below the other. It is your group’s responsibility to design and conduct an experiment whose data will support your answer to the driving question above. This document includes several ray tracings which can be used by students to do a take-home lab. Refraction and Snell's Law When an ultrasonic wave passes through an interface between two materials at an oblique angle, and the materials have different indices of refraction, both reflected and refracted waves are produced. Trace the outline of the glass slab, as in the diagram. The Law of Refraction - Snell's Law Discovered by Willebrord Snell in 1621 the laws of refraction are also termed as Snell’s law. Lab 9 - Reflection, Refraction and Total Internal Reflection This was the experiment: Part A) take a glass prism, and shine a single ray of light at it with a ray box, from specific angle of incdence (10 degrees - 70 degrees) then record the angle of refraction. Have you ever wondered what causes mirages, how lenses can focus light, or why your feet look closer and bigger in a pool of water than you know they are? Theory For light crossing the boundary between two transparent materials, Snell’s Law states: 1 1= 2 2 Where θ 1 is the angle of incidence, θ 2 is the angle of refraction, and 1 and 2 are the Experiment To Verify Snells Law. A physics 11 experiment on refraction and Snell's Law. Design and Conduct Your Experiment. As we know the refraction or bending of light takes place when it travels from medium to medium. This also occurs with light, which is why objects seen across an interface appear to be shifted relative to where they really are.
