Waves, Energy, and Information

How does sound energy travel?

• Sound energy travels in waves that need a solid, liquid, or gas to carry them.

• Sound energy travels in waves that can move through the vacuum of empty space.

• Sound energy travels in a straight line in one direction.

• Sound energy travels in a straight line that switches directions periodically.

True or False. Waves with a greater Amplitude have more energy than waves with a lower amplitude.
