The EJS Harmonics and Fourier Series model displays the sum of harmonics via a Fourier series to yield a new wave. The amplitude of each harmonic as well as the phase of that harmonic can be changed via sliders. In addition, several pre-set functions can be chosen to display. You can modify this simulation if you have EJS installed by right-clicking within the plot and selecting "Open EJS Model" from the pop-up menu item. (less)

The EJS Oscillator Chain model shows a one-dimensional linear array of coupled harmonic oscillators with fixed ends. This model can be used to study the propagation of waves in a continuous medium and the vibrational modes of a crystalline lattice. The EJS model shown here contains 31 coupled oscillators equally spaced within the interval [0, 2 pi] with fixed ends. (less)

This is a standards-aligned lesson plan for secondary education on the topic of mechanical wave motion. The lesson blends a six-minute video with a classroom activity that uses Slinky springs to model transverse and longitudinal waves. Explicit directions are given to support new or crossover teachers, including background information on wave energy and discussion questions. The resource was developed for use with the video <i>"Making Big Waves"</i>, which may be freely downloaded for classroom use. Teachers' Domain, a network partner of the National Science Digital Library (NSDL), is a growing collection of free educational resources compiled by researchers and experienced teachers to promote the use of digital resources in the classroom.

This is an interactive activity for middle school on the fundamentals of waves, adapted from the University of Utah's ASPIRE lab. It features animations of wave motion and a simulation that explores how a wave moves through different mediums. Students can adjust the density of the medium and choose to view longitudinal, transverse, or circular wave motion. The animation on water waves clearly depicts the movement of periodic waves, which can be difficult for learners to visualize. This resource also includes background information, discussion questions, and links to applicable national science education standards.

This activity is intended to supplement the "Wave on a String" PhET simulation. Students apply the concepts introduced in the computer simulation to explore properties of sinusoidal functions. They will find an equation of a wave with pre-set components and analyze how amplitude, frequency, and tension influence changes in the wave motion. The activity is intended to take ~60 minutes to complete. The wave simulation, which must be open and displayed to complete this activity, is available from PhET at: <a href="http://phet.colorado.edu/en/simulation/wave-on-a-string" target="_blank">Wave on a String</a>. This lesson is part of PhET (Physics Education Technology Project), a large collection of free interactive simulations for science education. (less)

This resource contains a set of eight introductory experiments on wave reflections, appropriate for use in high school and middle school. Use of the ripple tank can be a powerful tool to help students visualize wave behavior in general. In these basic experiments, students are introduced to ripple tanks and gain confidence in using them by doing some simple experiments with pulses. <i>SEE RELATED ITEMS</i> for a Teachers' Guide on using ripple tanks, and for ripple tank experiments for the more advanced classroom. This item is part of a much larger collection of physics/astronomy experiments, sponsored by the UK's Institute of Physics and funded by the Nuffield Curriculum Centre. (less)

This set of eight experiments introduces students to various categories of waves and the language used to describe them. Each experiment focuses on practical applications of wave motion and is supplemented with lesson procedures, drawings/photos, and tips for teachers. Especially noteworthy are the lab safety guidelines written specifically for each lab experiment. Background information accompanies each activity, as well.

Wave Machine Model

This model simulates the wave generating machine created by John Shive at Bell Laboratories and made famous by the <i>Similarities in Wave Behavior</i> film. The machine consists of horizontal cross-bars welded to a central wire spine that is perpendicular to the bars. The spine was constructed so that it can freely twist, allowing the cross-bars to produce wave-like patterns. The simulation allows various pulse shapes to be sent down the machine by selecting a function for the twist of the first rod or by dragging the first rod. The far end of the wave machine can be free or fixed, which changes the nature of the reflected wave. Change the lengths of the bars to simulate the effect of a wave propagating in a non-uniform medium. <i>The original film that introduced Dr. Shive's wave generating machine can be viewed at no cost: <a href="http://techchannel.att.com/play-video.cfm/2011/3/7/AT&T-Archives-Similarities-of-Wave-Behavior"target="_blank">Film: Similarities of Wave Behavior</a> (AT&T Archives and History Collection).</i> The Wave Machine model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. (less)

This research-based collection features a set of activity-based tutorials and worksheets on waves and optics, developed for introductory physics. It was designed to be implemented in student-centered cooperative learning environments. The tutorials feature thematic workshops across a broad range of topics relating to wave phenomena. <i>Workshop Tutorials</i> were deliberately designed to not be part of the formal assessment procedure, allowing students to openly discuss problems in physics and explore solutions in a stress-free environment. Solutions are provided to students as they leave the class, giving them immediate feedback on their ideas. All materials, including worksheets/solutions and activities, are available in Word and PDF formats. Created by the University of Sydney Physics Education Research group (SUPER) this item is part of a larger collection of activity-based physics tutorials. (less)
