Sound Waves

• What are sound waves?

  • caused by small variations in air pressure, carrying the energy
  • vibration at the source displaces the air in front, pushing it away then retreating
  • Leading to the formation of compressions and rarefactions
  • transmitting energy over large distances
• Sound waves are measured through an oscilloscope, where it picks up the waves through a microphone, converts it into an electrical signal and then displays as a transverse wave
