The type of wave that travels faster through solids than it does through gases is a sound wave.

Here's why:

* Sound waves are mechanical waves: This means they require a medium (like air, water, or solid) to travel.

* Solids are denser than gases: The particles in a solid are much closer together than in a gas. This means sound waves can travel faster through solids because the particles are closer and can transmit vibrations more efficiently.
