Charasteristics of Waves

• Displacement from the equilibrium. This shows the energy the wave can transfer.

  AMPLITUDE
• Has maximum positive amplitude. (highest point)

  CREST
• Has maximum negative amplitude. (Lowest point)

  TROUGH
• Particles are closest together.

  COMPRESSION
• Particles are farthest apart.

  RAREFACTIONS
• Length of a Complete wave

  WAVELENGTH ( λ )
• Number of waves per second, measured in Hertz (Hz)

  FREQUENCY (f)
• What is the formula for Frequency?

  f = 1/T or T = 1/f
• time to complete an entire wave.

  PERIOD (T)
• distance moved by a wave in a given time.

  SPEED
• Particles with equal displacements are _?

  IN PHASE
• Particles with equal displacements but in opposite directions are _?

  OUT OF PHASE
• What is the relationship between speed, frequency, and wavelength?


  v = fλ
• On the same medium, speed of wave is _?

  CONSTANT
• Both _ and _ adjust themselves to retain the _ of the wave

  FREQUENCY, WAVELENGTH, SPEED
• What can change the Speed of a Wave?

  CHANGING THE MEDIUM, FORCE ACTING ON THE MEDIUM
