The primary purpose of the lab is to study hookes law and simple harmonic motion by studying the behavior of a mass on a spring. Malus law, intensity, electric field and crossed polarizers. The objective of this lab is to determine the resistance of several resistors by applying ohms law. The experiment consists of a single thin bundle of light rays exiting a light box. The bending of a light ray as it passes from air to water is determined by snells law. In 1831, michael faraday showed that a changing magnetic field can induce an emf in a circuit. It is shown that the sizes of the angles of incidence and refraction are related to the speed of the light through the medium.
To demonstrate this, a volume of enclosed air located in a hollow metallic sphere. This law also applies to the bending of light by lenses and to the guiding of light by the fiber optic cables that carry modern communications signals. The physics classroom grants teachers and other users the right to print this pdf document and to download this pdf document for private use. A popular experiment in basic thermodynamics, both at a highschool and at university level, is the determination of the specific heat of solids and liquids using a. To use snells law to determine the index of refraction n of a piece of glass and to use it to find the speed of light in that glass. Snells law was used to calculate the angle of refraction. The polarization of light and the malus law using smartphones arxiv. A charles law experiment for beginning students journal of. Accumulator or battery eliminator, ammeter, voltmeter, rheostat, coil, connecting wires and key if necessary. In each of these two example problems, the angle of refraction is the variable to be determined.
With three of the four variables known, substitution into snells law followed by algebraic manipulation will lead to the answer. Students will also be introduced to the resistor color code and. Evaluation of experimental errors in boyles experiment scielo. Snells law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each.
Consider a conducting wire loop a closed circuit connected to. Ohms law deals with the relationship between voltage and current in an ideal conductor. Laser level, protractor, plate glass, plain paper, pencil, data sheet. This ray will be incident upon a d shaped dielectric so that we may deduce whether the laws of re. This will be verified in the experiment by measuring the light intensity using a light sensor.
