How does sound travel through different mediums?

Sound travels through different mediums by creating vibrations in the particles of that medium. When an object vibrates, it causes the surrounding particles to oscillate, compressing and rarefying the medium through which the sound is traveling. This propagation occurs through solids, liquids, and gases, but the speed at which sound travels varies depending on the density and elasticity of the medium.

In solids, particles are closely packed and can transmit vibrations efficiently, resulting in faster sound travel compared to liquids and gases. In liquids, the particles are further apart than in solids but still relatively close, enabling sound to travel more quickly than in gases, where the particles are the most dispersed.

Thus, the correct option illustrates that sound is fundamentally reliant on particle vibrations within a medium to propagate, distinguishing it from electromagnetic waves, which can travel through a vacuum.
