Dry air. The lower the density, the more slowly sound travels. Dry air is the least dense of all the materials listed.
wood
Water:)
Sound energy can travel through solids more slowly than through liquids and gases. This is because the particles in solids are more closely packed, causing sound waves to propagate at a slower speed due to increased interaction between particles. Examples of materials that sound energy can travel through slowly include metals, wood, and concrete.
That completely depends on what "slowly" means to you.Sound propagating through iron is quite slow compared to the speed of lightin vacuum, but is substantially faster than the same sound in air.
Vibration can travel through solids, liquids, and gases. In solids, such as metal or wood, vibrations travel quickly due to the close arrangement of particles. In liquids and gases, such as water or air, vibrations travel more slowly but can still propagate.
Sound travels more slowly in denser materials because the particles in these materials are closer together, causing sound waves to propagate more slowly compared to materials with less dense particles. This results in a longer response time for sound to travel through denser mediums.
Sound cannot travel through a vacuum because it requires a medium (solid, liquid, or gas) for transmission. So, in a vacuum, sound waves cannot propagate.
Impulses travel more slowly through unmyelinated nerve fiber.
Yes it can cause sound waves can travel through solids,liquids,but slowly in gases and air

An hot air balloon i think.
outercore
it traps air inside to slow it down
Longitudinal (also know as compression) waves travel more slowly through gasses than solids.
No
Probably very slowly, mostly following migrating food sources.
Light waves travel faster through air than through water because air has a lower refractive index than water. This means that light waves experience less bending (refraction) in air compared to water, allowing them to move faster.
