Transverse + Longitudinal + description

Cards (17)

  • a wave = a transfer of energy
  • two types of waves = transverse + longitudinal
  • Transverse = light =vibrations (oscillate) are 90 degrees to motion
  • Longitudinal waves = sound = oscillates on the same plane as motion
  • Longitudinal = if you push that way, it'll go that way (like dominoes)
  • Transverse = up and down (like a mexican wave; up and across)
  • peak / crest = highest point of wave
  • Trough = lowest point of a wave
  • Wavelength (λ) = distance between two waves (from peak to peak or trough to trough)
  • amplitude = height (depth) of a wave
  • Frequency (Hz) = amount of waves per second
  • 50hz = 50 waves per second
  • wavespeed = speed of a wave(m/s)
  • Time period = how long it takes for one wave to pass
  • 1 wave = 1 peak + 1 trough
  • 120Hz = 120 waves per second
  • to calculate wavelength : total distance / amount of waves
