Sound is a wave- waves pass through a medium by disturbing adjacent molecules in the medium and causing displacement of these molecules. The displacement of these molecules in turn causes displacement of more molecules, and thus the wave propagates.
For example, you say something to someone (an example more common day). This is a sound wave in air. The air molecules right in front of you get displaced, and begin to move up and down. Do the air molecules right in front of you actually move to the other person? No, instead their displacement causes displacement of other molecules, which gets passed along in a chain reaction manner until the molecules around the other person are displaced. In this manner, a wave propagates.
Sound waves propagate through matter in the same way, except since the molecules are closer together than in a gas or liquid the wave can move faster. Thus, waves move faster in solids than in liquids or gas.
Sound waves travel through the three states of matter (gas, liquid and solid) by vibrations.
Sound travels slower through less dense matter because sound is the result of molecules hitting each other. When there are fewer molecules for the vibrating molecules to bump into, sound travels slower.
Sound requires particles to travel through, but dark matter is believed to be non-interacting, meaning it doesn't interact with the particles that carry sound waves. This lack of interaction prevents sound waves from propagating through dark matter.
It depends. Is it a mechanical wave or a electromagnetic wave? Mechanical waves (for example sound waves) travel trough every state of matter and they can't exist without matter. They don't travel through vacuum. Electromagnetic waves travel trough space and get interrupted only by other electromagnetic waves.
yes
A perfect vacuum
Solid, Liquid and Gas... These are the three things a sound wave can get trough... A sound-wave can get trough solid easily, because of all the particles, after that trough Liquid and at least trough Gas...

No, because there is no substance to propagate.
The lowest point on a sound wave is the trough, which represents the lowest amplitude or pressure point in the wave. In a light wave, the lowest point is the trough as well, representing the lowest intensity or energy level of the wave.
Sound is not made up of matter; it is a disturbance that travels through a medium, such as air or water. Light, on the other hand, is made up of electromagnetic waves, which are forms of energy rather than matter.
