Sound

Sound lets you show at a particle level how sound waves travel through a medium. You’ll use it to cover:

• How areas of compression and rarefaction make sound waves

• How changing frequency or amplitude affects sound waves

• How the behaviour of sound waves changes in different mediums

• How an oscilloscope can monitor a sound wave

• How energy dissipates as a sound wave spreads out from a source

• The relationship between simple sounds and musical notes
