Lab 8: Reflection and Refraction
Purpose: The purpose of this experiment is to practice applying two fundamental
laws of geometric optics. These laws are the law of reflection and the law of
refraction. This lab will help students get hands on experience
Magnetic Fields & Electromagnetic Induction
Purpose: Student will learn about magnetism and electromagnetic radiation by inducing a
current flow through a magnetic field. Students can use and relate their knowledge from
experience with microwaves, compute
Purpose: The purpose of todays lab is to get hands on experience with diffraction
and interference effects that are produced through a double slit.
Theory: This lab follows the figure 12.1 for a double slit. There is a distance R from a
screen and a laser
