physics

• Destructive Interference 


  Occurs when a wave becomes smaller due to mixing with another wave
• Diffraction 


  when a wave bends around the edge of an opening ;the spreading out of waves as they pass through an aperture or around objects. 
• Refraction 


  When a wave changes direction due to a medium change
• Constructive Interference

  When a wave becomes larger due to mixing with another wave
• wavelength 


  the distance between a point on a wave and the same point on the next cycle of that wave
• p-wave 


  its an example of a longitudinal wave
• travels through solids only

  S-waves
• when the crest of one wave passes thru the trough of another wave __ takes place

  destructive interference
• fastest kind of seismic wave

  P-waves
• The speed of sound is determined by the temperature, pressure and density of the medium it travels through.
• whats the amplitude of a wave

  the size of the particle vibration
• When a sound wave has destructive interference a quieter sound is produced
