Watch it. Interact with it. Change a variable and observe the result. Explore and learn. These are the types of tasks that learners engage in when they're face-to-face with one of our Interactives. These variable-rich environments allow a learner to observe physics principles and draw their own conclusions about the manner In which the physical world operates. Today we feature three such simulations pertaining to the topic of Waves and Sound:
1. Slinky Lab
Grab a particle on a string and start wiggling it back and forth. Watch as the disturbance you create travels from particle to particle. Explore the result of wiggling more or less frequently or with a smaller or larger amplitude. Change the amount of damping effects and other variables. You'll have so much fun with Slinky Lab that you might forget that you're learning physics.
2. Wave Simulator
Prepare yourself because you are about to observe a virtual wave machine. You can set it vibrating at any frequency and any amplitude you wish. You can even view it simulating a sound wave. Watch it vibrate in slow motion. Watch it in fast motion. Watch it in real time. And watch the clock because you're going to be so captivated that you might be late for your next class.
3. Standing Wave Maker
If you have ever seen a standing wave demonstration, then you have seen the definition of groovy (excuse the 80s term). And groovy is what you will see when you open this simulation. Make standing waves from several pre-set conditions or set the conditions yourself. View two waves traveling in opposite directions and the standing wave pattern that results from their interference. Don't forget to say Groovy!
