Cards (15)

  • What equipment is used in Method 1 for the experiment?
    Signal generator, string, weights, pulley
  • What is the purpose of the signal generator in Method 1?
    To produce and adjust the frequency of oscillations
  • How long should the string be in Method 1?
    Between 1-2 meters
  • What is the first step in Method 1 after setting up the equipment?
    Measure the length of the string with a metre ruler
  • What weight increments are used in Method 1?
    2N increments up to 12N
  • How is tension adjusted in Method 1?
    By adding more weights to the end
  • What type of wave pattern should be produced in Method 1?
    Clear standing wave of the first harmonic
  • What should be plotted after obtaining readings in Method 1?
    Graph of f against T or f against T
  • What is the main equipment used in Method 2?
    Sonometer, tuning forks, paper rider
  • What is the purpose of the paper rider in Method 2?
    To indicate when the first harmonic is produced
  • How is vibration created in Method 2?
    By striking a tuning fork on a rubber bung
  • What adjustment is made to the string in Method 2?
    Adjust tension using the tightening nut
  • What should be recorded in Method 2 after adjusting tension?
    Tension from the newtonmeter and tuning fork frequency
  • What should be done after measuring different tuning fork frequencies in Method 2?
    Plot a graph of f against √T or f against T
  • How can mass per unit length be determined in both methods?
    By measuring total string mass and dividing by length
