A seismologist who studies earthquakes sees that a seismic wave that traveled 500 km through Earth changed
speeds multiple times. What conclusion can be drawn from this observation? (1 point)
O The seismic wave's wavelength remained constant.
O The seismic wave's frequency also changed multiple times.
O As the wave passed through less dense material, the wavelength decreased.
o As the wave passed through less dense material, the speed of the wave increased.
