waves in a solid

• What apparatus is used to measure waves in a solid?

  A string with a vibration generator
• What keeps the string taut in the apparatus?

  A hanging mass
• What does the signal generator do in the setup?

  Changes the frequency of vibration
• What is a standing wave?

  A wave formed due to resonance
• In which instruments do we find standing waves?

  Stringed musical instruments like guitars
• How do you measure the wavelength of a standing wave?

  Measure total length from bridge to generator
• What is the wave equation used to calculate wave speed?

  Wave speed = frequency × wavelength
• What happens to the standing wave when the frequency increases?

  It changes to have more 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?

  Tautness of the string and mass per centimeter
• What are the key factors affecting wave speed in a string?

  • Tautness of the string
  • Mass per centimeter of the string
• What is the relationship between frequency, wavelength, and wave speed?

  • Wave speed = frequency × wavelength
