1
New cards

  • define fundamental mode of vibration (1st harmonic)


  • minimum frequency of stationary wave through a material


2
New cards

  • explain how a stationary wave is produced on a stretched spring


  • string is stretched between two points

    • points act as nodes

  • string is plucked

    • produces a progressive wave

      • travels along the string

      • reflects off the points

        • produces two progressive waves

        • superpose and produces a stationary wave


3
New cards

  • state the fundamental wavelength of a stationary wave on a stretched string

  • state the relationship between the wavelength and the length of the spring


  • ½λ

  • λ = 2 × length of the string


4
New cards

  • state the possible harmonics of a stretched string


  • all integer multiples of the fundamental frequency
