125 Physics Projects For The Evil Genius - Plot & Excerpts
For this reason, water waves can be useful in studying wave properties in general. A ripple tank provides a simple, convenient way to produce and study waves and the various types of obstacles they can encounter. What You Need shallow tray or tank with a transparent bottom or commercially available ripple tank water bright light that can be held or mounted above the tank one or several plain sheets of white poster board to serve as a screen on which to view the images produced by the ripple tank various props including a straight wall, a curved wall, a thick glass plate about one-half the thickness of the water in the tank, a cup, a pencil, and a manual or mechanical source of ripples optional: a way to project the shadows generated, such as an overhead project or a video monitor Method Basic wave generation Set up the tank with the light overhead. The shadow pattern should be visible on the floor. Adjust the height of the light above the tank and the screen below the tank to give the best focus of the shadows from the ripples on the floor.
