Tuning fork as “simple” sound
Video (00:10 minutes):
Example of a simple periodic sound signal is the relatively pure sound of a tuning fork. The video shows the oscilloscope graph!
Information and ideas:
Suitable for demonstration purposes but also good for self-study on the part of the students. Idea: show the video without sound to begin with. The students should then guess what sort of noise/sound it might be.
Relevant for teaching:
Communication and understanding
Vibrations and waves
