Transverse + Longitudinal + description

• 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
