Sound wave travel fastest in
Answers
Liquids are not packed as tightly. And gases are very loosely packed. This enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air.
Solids are the correct answer for your question.
Sound travels by bumping on different molecules causing a local disturbance. The sound wave can travel faster in the solid surface rather than in liquid and gas. Solids have densely packed molecules than liquids and gases. So it becomes easy for the sound wave to bump on to each molecule with little efforts.
Liquids are the second fastest medium that sound can travel. Liquids have molecules that are packed with less dense. So it becomes little hard for a sound wave to travel through but it make faster in a liquid medium than in gaseous medium where the particles are completely freed up.
