Physics Narrative for 11-14 Supporting Physics Teaching

A recap

Sound consists of audible vibrations, which travel from a source to a detector.

These vibrations travel out from the source at a speed that depends on the medium, which must contain particles. The medium must therefore be a solid, liquid or gas. Sounds do not travel through a vacuum.
