Experiment A

Introduction The name dipole is given to a bar magnet since the magnet has two poles, that is, South and North. In case a magnet is broken into two, creation of two isolated poles never exist because the individual fragment still contain two poles. Magnetic monopoles do not exist hence the simplest magnetic field source is the dipole. Baxis, magnetic field, for an ideal dipole is given by Baxis=µ04π=2µd3

Lab Report

Introduction The purpose of the experiment was to show how prism separates white light into its component colors and to show how different colors are refracted at different angles through a prism. It was hypothesized that violet color would be the most refracted because it had the lowest wavelength.

Materials

- Light source - Trapezoid from Ray Optics Kit - Blank White Paper

Procedure

The light source was placed in a ray box mode on a sheet of blank white paper and a single white ray was selected by turning the wheel. Trapezoid was positioned such that its acute angle side faced ...

Introduction

The purpose of this lab experiment is to investigate the laws of reflection and refraction. Determine the relationship between: distance of an object in front and the distance of the image behind, the angle of incidence and the angle of reflection of different light rays.

Θ1 = Θ2The angle of incidence equals the angle of refraction. n = c / v The index of refraction, the speed is faster in a vacuum than in a material. n1 sin Θ1 = n2 sin Θ2The rays of light bend when either entering or leaving through water and traveling through the air. When light/rays pass through ...
