A tuning fork vibrating in air produces sound waves. These waves are best classified as

• longitudinal, because the air molecules are vibrating parallel to the direction of wave motion 
• longitudinal, because the air molecules are vibrating perpendicular to the direction of wave motion 
  
• transverse, because the air molecules are vibrating parallel to the direction of wave motion 
  
• transverse, because the air molecules are vibrating perpendicular to the direction of wave motion
