This illustration shows a sound wave traveling from a tuning fork through a medium. How can the wavelength be determined?

• by comparing the width of the bands at X and at Y

• by comparing the number of particles at X and at Y

• by measuring the distance between two points labeled X

• by measuring the distance between a point labeled X and a point labeled Y

  by measuring the distance between a point labeled X and a point labeled Y
