Introduction: For this lab, the main objective is to observe the properties of projectile motion. Because
the motion will be occurring at set, predetermined initial velocities, it wi

DIFFRACTION AND INTERFERENCE
In this experiment you will demonstrate the wave nature of light by investigating
how light bends around edges and how it interferes constructively and destructively. You
will observe these effects in a variety of situations a

In this experiment, the activity will be based on a Phet simulation called

Boulder. This group has a number of good simulations of vario
