Sound waves move out in a circular pattern.
Sound waves look like circles rippling out but under closer investigation they look like this:
This is a wave created by a high note.
Notice that the high sound wave is close together
This is a wave created by a low note.
Notice that the low sound wave is far apart.
High and Low sound waves A high sound waveA low sound wave
High and low waves are the same height. Notice that the high wave is close together and the low wave is far apart.
Soft and Loud Sound Waves A soft sound waveA loud sound wave
Soft and loud sound waves together. Notice that the waves are the same only one is taller.
Oscilloscope Traces. Looking at sound waves You cant see a sound wave. But you can use an oscilloscope to make a trace which looks the same as the sound.
