6. If an obstacle is much larger than the wavelength of a wave, almost no (refraction, reflection,
diffraction) occurs.
7. When you shake a rope up and down, you create a transverse, compressional, seismic) wave.
8. When part of Earth's crust breaks, (seismic, tidal, uniform) waves pass through Earth.
9. In a given medium, as the frequency of a wave increases, its speed (increases, decreases,
remains the same).
10. In a standing wave, the point at which the medium doesn't move is called the (antinode,
node, compression).
