- The equilibrium positions of six particles in a medium are separated by a distance of 2 cm as shown. [Figure shows six particles at 0, 2, 4, 6, 8, 10 cm.]
The positions of these particles, when a longitudinal wave is transmitted through the medium, are now shown. [Figure shows particles shifted from equilibrium positions.]
What is the wavelength of the wave?
six particles at equal spacing before and after a longitudinal wave
