transverse and longitdutional wave

• What are the two types of waves?

  Longitudinal

  Transverse
• What do all waves do?

  Transfer energy from one place to another.
• What is it called when a transverse wave moves up and down?

  Oscillations

  
• What is the main definition of transverse waves?

  In transverse waves, the oscillations are perpendicular to the direction of energy transfer.
• Explain compression in longitudinal waves:

  This is when the air particles are close together.

  
• What is the main definition of longitudinal waves?

  In longitudinal waves, the oscillations are parallel to the direction of energy transfer
