Wave

• A disturbance in a medium that carries energy without a net movement of particles.

• The water in the ocean

• 
• The channel that carries energy through things while staying perfectly in tact.

Longitudinal wave

• 
• 
• 
• 

Transverse wave

• 
• 
•

Sound

• What you hear

• Vibration of vocal cords only that travels into peoples ears

• Vibrations projected and transmitted through solids, liquids and gasses. 

• Whenever anything vibrates it makes sound, even if its inaudible.

Compression

• The part in the longitudinal wave where the particles are farthest apart

• The part in the longitudinal wave where the particles are closest together

• When the particles are closest together

• The part in the transverse wave where the particles are farthest apart

Rarefaction

• The part in the longitudinal wave where the particles are farthest apart

• When the particles are furthest apart

• The part in the longitudinal wave where the particles are closest together

• The part in the transverse wave where the particles are farthest apart

Crest

•  The highest part of the transverse wave, above the midpoint

• The lowest part of the transverse wave, above the midpoint

• The highest part of the longitudinal wave, above the midpoint

• How you measure in Hertz
