Waves

• Parts of a wave.

  A) Crest

  B) Wavelength

  C) Amplitude

  D) Trough

  E) Equilibrium

  
• The absence of a disturbance.

  Equilibrium
• This refers to the maximum amount of a displacement on the medium from its rest position.

  Amplitude
• The maximum amount of positive or upward displacement from the rest position.

  Crest
• Distance from crest to crest and tough to trough.

  Wavelength
• The maximum amount of negative or downward displacement on the medium from its rest position.

  Trough
• Described as a disturbance that travels through a medium from one location to one another location.

  Wave
• An alteration or displacement of a region of a medium from its equilibrium state.

  Disturbance
• A single disturbance moving through a medium from one location to another.

  Pulse
• Refers to how often the particles of the medium vibrate when a wave passes through the medium.

  Frequency
• The time for a particle on a medium to make one complete vibrational cycle.

  Period
• A complete vibration. The complete event starting with a rise from zero energy to a maximum amplitude.

  Cycle
• A category of wave in which particles of the medium move in a direction PERPENDICULAR to the direction that the wave moves.

  Transverse wave
• A wave in which particles of the medium move in a direction PARALLEL to the direction that the wave moves.

  Longitudinal wave
• Wave by movement.

  Transverse wave
• A wave that is capable of transmitting its energy through a vacuum of outer space.

  Electromagnetic wave
• A wave that needs a medium.

  Mechanical wave
• A wave that is not capable of transmitting its energy through a vacuum.
