This page provides a set of context-rich physics problems relating to waves and oscillations . Each context-rich problem is based on a real-world situation, and includes both information that is relevant to solving the problem and extraneous information. Strategies for problem solving are not explicitly provided. Each problem is formulated so it is too difficult for one student to solve alone, yet not too difficult for a group to master. This resource is based on the research results of the Minnesota Physics Education Research group. See Related items on this page for a link to the full collection. (less)

The Driven Wave Machine model simulates a wave machine driven by a sinusoidal oscillator. The machine consists of horizontal bars welded to a torsion rod that is perpendicular to the bars. The simulation allows the user to change the number of bars, the drive frequency, and the boundary conditions. The simulation also allows the user to change the lengths of the bars, thereby simulating the effect of a wave propagating in a non-uniform medium. The Driven Wave Machine model is a supplemental simulation for the article <a href="http://dx.doi.org/10.1119/1.3543575">"Standing Waves in a Nonuniform Medium"</a> by Paul Gluck in The Physics Teacher 49(2), 76-77 (2011) and has been approved by the authors and The Physics Teacher editor. The Driven Wave Machine model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_mech_osc_chains_DrivenWaveMachine.jar file will run the program if Java is installed. (less)

The EjsS Wave Illustration Package contains JavaScript adaptations of Physlet Illustrations from Physlet Physics Chapter 17. Students need to interact with the Physlet, but the answers to the wave questions posed in the Illustration are given or are easily determined from interacting with it. Some Illustrations provide examples of physics applications while others are designed to introduce a particular wave function concept. Typical uses of Illustrations would include reading assignments prior to class and classroom demonstrations. The EjsS Wave Illustration Package was developed using the Easy Java/JavaScript Simulations (EjsS) version 5. Although EjsS is a Java program, it can create stand alone JavaScript programs that run in almost any PC or tablet. EjsS can also create ePub documents containing multiple simulations. (less)

The EJS Wave Representations model displays two representations of a sinusoidal wave on a string. One shows a movie of the wave traveling along a string - you can think of this representation as a sequence of photographs. The second representation is a plot of the displacement as a function of time for two points on the string (you can select which two points to use). Using only these two representations, you can determine the values of many different parameters that describe the wave. (less)

Evidence of embodied cognition about wave propagation

That students think of wavepulses as if throwing balls down a long taut spring is well established. Typical questions involve students imagining the spring already pulled taut; a different scenario would imagine them pulling the spring tight first. This situation creates a different baseline of physical experience from which to reason. For example, it provides a physical experience in which tension is a relevant measure in the system. We investigated the effects of students pulling the spring (or not) in interviews after instruction. We also wrote two surveys, each giving a different physical description of a typical problem. From interviews, we find evidence that a different embodiment of the problem affects students' responses. In surveys, with students asked to imagine different situations, we found no such evidence.

Illinois PER Interactive Examples: Waves on a Slinky

This is an interactive homework problem relating to transverse wave motion in ... (more)

This is an interactive homework problem relating to transverse wave motion in a vibrating Slinky toy. A slinky of known mass is stretched to a length of 6m and given a shake to create a transverse wave pulse. It takes 0.8 seconds for the pulse to travel the full length. If the Slinky is stretched to a length of 10.2m, how long will it take the pulse to reach the other end? The problem is accompanied by a Socratic-dialog "help" sequence designed to help users understand the relationships among spring tension, spring constant, and speed of a traveling wave. Specific guidance is provided for each component of this problem, from strategic analysis through application of the mathematics. This item is part of a larger collection of interactive problems developed by the Illinois Physics Education Research Group. <b>SEE RELATED ITEMS BELOW</b> for a link to the author's full set of problems for an introductory physics course on Mechanics and Heat.

This page contains a set of three short video clips of wave pulses on a slinky spring. One shows a single pulse reflected from a fixed end, the second shows two pulses passing over each other, and the third is a longitudinal pulse. LivePhoto Physics uses high-speed DV format videography in which action may be stepped frame-by-frame, thus enabling easy use of video analysis software. The videos are 10-30 frames in length and may be viewed in step motion or real-time. Position and time data may be measured and collected by using video-analysis tools. See related items on this page for a link to download free Tracker video analysis software. Tracker allows students to not only analyze the video in slow-motion, but also to overlay the videos with dynamical models to see how well the model matches the real world. This video is part of a larger collection of short physics videos developed by the Rochester Institute of Technology Live Photo Physics Project. (less)
