Which best describes a transverse wave?

• a wave that causes the medium to vibrate at right angles to the direction in which the wave travels. 
• a wave in which the vibration of the medium is parallel to, or in the same direction as, the direction in which the wave travels. 
• a wave in which the vibration of the medium travels along the surface separating two mediums, air and water.
• None of the above. 

Which best describes a longitudinal wave?

• a wave that causes the medium to vibrate at right angles to the direction in which the wave travels. 
• a wave in which the vibration of the medium is parallel to, or in the same direction as, the direction in which the wave travels. 
• a wave in which the vibration of the medium travels along the surface separating two mediums, air and water.
• None of the above. 

When a longitudinal wave carries energy through a spring, the area where the coils of a spring are closer together that they would be in rest position is called ___.

• rarefaction
• compression
