Question

Arianna is experimenting with different materials to see which one will
transmit sound the fastest. Through which of the following materials will sound waves
travel the fastest?

Water

Oil

Concrete

Air

Answer 1

Answer:

Concrete

Explanation:

The speed at which sound propagates is medium dependent. As one of the forms of mechanical waves, sound requires a material medium for propagation from place to place.

• Sound travels with the least speed in air because air particles are far apart and they are randomized.
• Sound travels with the greatest speed in solids. Concrete is the only solid material given in the choice.

The speed of sound increases from air to liquid and to solid.
