Every Saturday we highlight three resources that have received particularly heavy traffic from website visitors during the past week. This week's winners are …
1.Frequency and Period of a Wave at The Tutorial
The Waves chapter has been showing some rather significant traffic in the past few weeks. Pages such as the Frequency and Period of a Wave have begun to show up among the most popular of pages on our website. Like all our Tutorial pages, concepts are introduced in an easy-to-understand language and supported by informative graphics. The page ends with a Check Your Understanding section that allows learners to conduct a self-assessment.
2. Interference Concept Builder
The Wave Interference Concept Builder targets student understanding of what interference is, of the distinction between constructive and destructive interference, and of how the principle of superposition can be used to determine the shape of the resultant wave (or wave sum) that results from the interference of two waves. There are 20 total questions organized into 10 different Question Groups and spread across three different activities. The activities are titled To Construct or To Destruct, The Principle of Superposition, and Sum It Up.
3. Simple Wave Simulator at The Physics Interactives
This week's top Interactive was the Simple Wave Simulator Interactive. This Interactive is part of our Waves and Sound collection. The Interactive allows learners to explore wave mathematics and concepts. The simulator depicts a traveling wave on a rope or a sound wave moving through a column of air. Users can alter the frequency, speed and amplitude of the wave and see immediate changes in the simulation. The distinction between particle motion and wave motion is immediately obvious as learners watch the disturbance move and three "tagged" particles vibrate about a fixed position. The Interactive works well on tablets such as the iPad, on Chromebooks, and on mobile devices.
