waves

• between two nodes is half a wavelength
• between a node and an antinode the wavelength is a quarter
• speed = tension / mass per metre
• superposition is when two waves meet at one point the resultant displacement at that point is equal to the sum of the displacements of the individual waves at that point
• a progressive wave is a wave that moves from one place to another
• waves transfer energy from one place to another
• stationary wave:

  • same speed
  • same wavelength
  • same frequency
  • travelling in different directions
• monochromatic means one wavelength
