Question

____· the transfer of ____ from one place to another
another
sound ______ move by compressing molecules.
wave diagram (wavy line over a bottle with molecules and an ear)
____· the ____ of a wave.
this determines ____ of a ____
amplitude diagrams: left labeled \quieter (strong vibrations)\ with smaller amplitude, right labeled \louder (weak vibrations)\ with larger amplitude

Explanation:

1. First blank (top): "Wave" - transfer of energy. Second: "energy". Sound "waves" move by compressing molecules.
2. Lower blank: "Amplitude" - height of wave. Determines "loudness" (note: image has a typo, louder should be strong, quieter weak; correct: amplitude determines loudness, with larger amplitude = louder (strong vibrations), smaller = quieter (weak)). Of a "sound" (or "wave").

Answer:

Top: Wave - The transfer of energy from one place to another; Sound waves move by compressing Molecules.
Bottom: Amplitude - The height of a wave. This determines loudness of a sound (Note: Image has a typo in vibration labels; larger amplitude = strong vibrations (louder), smaller = weak (quieter)).
