Based on the information in Figure 1 and Table 1, which statement best compares a sound wave in a vacuum to a sound wave in air?

• A sound wave in a vacuum travels much faster than a sound wave in air because there are no molecules to slow it down.

• A sound wave in air travels much slower than a sound wave in a vacuum because of the number of molecules in air.

• A sound wave cannot travel in a vacuum because there are no molecules to transfer the energy.

• A sound wave travels at the same speed in a vacuum as a sound wave in air does.
