Option 1: Air

Sound travels slowest through air compared to the other materials listed. This is because air is less dense compared to other substances. As sound waves propagate through a medium, they interact with the molecules of the medium, causing them to vibrate and transfer the sound energy. In less dense materials like air, the molecules are more spread out, leading to a lower density. Due to this lower density, the molecules are further apart and take longer to interact with the sound waves, resulting in a slower speed of sound transmission.

Option 2: Glass

Sound travels faster in glass compared to air. Glass is denser than air, and the molecules are closer together. As a result, sound waves can interact more frequently with the glass molecules, leading to a faster speed of sound transmission.

Option 3: Water

Sound travels faster in water compared to air. Just like glass, water is denser than air, and the molecules are closer together. As a result, sound waves can interact more frequently with the water molecules, resulting in a faster speed of sound transmission.

Option 4: Wood

Sound travels faster in wood compared to air. Wood is also denser than air, and the molecules in wood are tightly packed. This density allows sound waves
