A high pitch sound has a high frequency and makes the air vibrate quickly , so the wave peaks are closer together. A low pitch sound makes the air particles vibrate more slowly and so the peaks ...

It describes how sound waves are created through vibrations, how they can be visualized using electrical devices, and how different frequencies affect pitch. The film demonstrates the properties ...

This experiment demonstrates how water affects sound waves and pitch. You'll discover how different water ... it pushes and pulls on nearby air molecules, creating areas of high and low pressure.
