In this Mystery, we investigate how different wave lengths can create different pitches in sound. This Mystery is two worksheets, an activity with a rope, and a series of online videos. This mystery has a lot of extension activities associated and websites linked at the end which will further the depth and amplitude of the activity.
Since sounds are vibrations, this activity helps to visualize the different pitches of sound. If this sounds good to you, I urge you to check out the web based oscillator linked at the end of the mystery. You can even recreate the whistle from the video. I’d recommend this activity for anyone looking to catch a wave, a soundwave.
