Sound travels in mechanical waves. A mechanical wave is a disturbance that moves and transports energy from one place to another through a medium. In sound, the disturbance is a vibrating object.
And the medium can be any series of interconnected and interactive particles. This means that sound can travel through gases, liquids and solids. Let's take a look at an example. Imagine a church bell. When a bell rings, it vibrates, which means the bell itself flexes inward and outward very rapidly. As the bell moves outward, it pushes against particles of air.
Those air particles then push against other adjacent air particles, and so on. As the bell flexes inward, it pulls against the adjacent air particles, and they, in turn, pull against other air particles. This push and pull pattern is a sound wave.
The whole process is pretty complex. I'm too sleepy to write a fully making-sense review atm, so this should do for now! And, although I was a little dissapointed with some characters, I really did enjoy Settling, and would definitely reccomend that you read Solid! Which brings me to my biggest complaint of the book: I went through a series of emotions while reading Settling - excited at the start, a little disappointed around the middle and awestruck at the end. Read more Read less. Shelley knows how to write a series that will keep readers coming back book after book.
The vibrating bell is the original disturbance, and the air particles are the medium. Sound isn't restricted to moving through the air.

Press your ear against a solid surface like a table and close your eyes. Tell someone else to tap his or her finger on the other end of the table. The tapping becomes the initial disturbance.
The sound moves through a medium by alternately contracting and expanding parts of the medium it is travelling through. The speed of sound is the distance which is travelled per unit time by any sound wave which can be measured. The speed of sound is an essential parameter used in a variety of field in Physics. The speed of sound refers to the distance travelled per unit time by a sound wave propagating through a medium.
The speed of sound when travelling through air at 20oC is The speed of sound in gases is proportional to the square root of the absolute temperature measured in Kelvin but it is independent of the frequency of the sound wave or the pressure and the density of the medium. But none of the gases we find in real life are ideal gases and this causes the properties to slightly change. Sound can travel through wood too! In fact, sound likes travelling through solid more.
In the olden days, doctors used stethoscopes consisting of thin wooden rods with broadened ends and they worked exactly like our modern ones and performed just as well. How can sound travel through solids?
Sound is nothing more than a disturbance which is propagated by the collisions between the particles; one molecule hitting the next and so forth. Solids are significantly denser than liquids or gases. This means that the molecules are closer to each other in solids than in liquids and in liquids than in gases. This closeness due to density means that they can collide very quickly. Effectively it takes less time for a molecule of a solid to bump into its neighbouring molecule. Due to this advantage, the speed of sound in a solid is larger than in gas.
Similarly, the density of a liquid is greater than the density of a gas. Therefore the distances between molecules is more in liquids than in solids but is less than in gases.
Hence speed of sound in liquids lies in between the speed of sound in solids and gases. We should remember that the speed of sound is independent of the density of the medium when it enters a liquid or solid.
