wave length

• Amplitude


  The maximum distance that the particles of a wave's medium vibrate from their rest position
• Wavelength


  The distance from any poiont on a wave to an identical point on the next wave
• Frequency


  The number of waves produced in a given amount of time.
• Reflection


  The bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
• Echo


  Reflected sound wave
• Transmission


  Waves passing through an object
• Refraction


  The bending of a wave as the wave passes between two substances in which the speed of the wave differs
• Diffraction


  A change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening
• Interference


  The combination of two or more waves that results in a single wave
• Constructive Interference


  Occurs when the crests of one wave overlaps the crests of another wave. The troughs also overlap. This results in a wave with a higher crest and a lower trough.
• Destructive Interference


  Occurs when the crests of one wave and the troughs of another wave overlap. This results in a smaller amplitude or no wave at all.
• Standing Wave


  A pattern of vibration that simulates a wave that is standing still
• Resonance


  A phenomenon that occurs when two objects naturally vibrate at the same frequency; the sound produced by one object causes the other object to vibrate.
