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
A sound wave in a vacuum travels much faster than a sound
wave in air because there are no molecules to slow it down.
B
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.
D
A sound wave travels at the same speed in a vacuum as a
sound wave in air does.
