waves in a solid

• What is the purpose of the vibration generator in the experiment?

  To create vibrations in the string
• What is the length of the standing wave measured in the experiment?

  21.5 centimeters
• How do you convert 21.5 centimeters to meters?

  0.215 meters
• What happens to the standing wave when the frequency is increased?

  It changes to have more half wavelengths
• How many half wavelengths are shown in the new standing wave?

  Three half wavelengths
• How do you calculate the wavelength from the total length and number of half wavelengths?

  Divide total length by half wavelengths, then multiply by 2
• What does the wave speed depend on in the string experiment?

  Tautness of the string and mass per centimeter
• What are the steps to measure the features of waves in a solid?

  • Use a string attached to a vibration generator
  • Keep the string taut with a hanging mass
  • Measure the total length of the standing wave
  • Use the wave equation to calculate speed
• What is the relationship between frequency, wavelength, and wave speed in the experiment?

  • Wave speed = frequency × wavelength
  • Increasing frequency changes the standing wave pattern
  • Wave speed remains constant for a given string tension
