Question

Explain how sound waves travel?

Answer 1

Sounds are produced by vibrations. An object vibrates it cause when
movement in the air particles. The movement is called Sound waves. It travels as waves, which are vibrating particles and reflected by surfaces. Sound waves travel $343m/s$ through the air and faster through liquids and solids. The louder sounds are made by bigger vibrations.

Complete step by step answer:
Sound waves are longitudinal waves and they travel through a medium. Sound waves are caused by the particles of the medium vibrating parallel to the direction of wave travel. The vibration travels through solids, liquids, and gases.
Sound waves travel $343m/s$ through the air. The sound waves transfer energy from a source of the sound e.g. a drum and to surroundings. When vibrating the air particles which you air detect the sound waves. Hard surfaces reflect the sound well and it makes echoes. Soft surfaces like carpets reflect very little sound.
Sound vibrations traveling through the air:
The vibrating sound source moves that the air around it is also made. Imagine a drum skin being hit hard with a beater then the skin moves to one side and compresses the air. The compressing effect, therefore, moves outwards from the sound sources. The movement of the air is a faster vibration. The movements of the effect outwards are in a waveform. The effect reaches the ear and makes signals which are sent to the brain. Sound vibrations travel outwards in all directions from a sound source.

Note:
Sound waves cannot travel through a vacuum because the vacuum is an area without air-like space. Because there is no matter for the vibrations to work into made sound waves.
The sound wave shapes with no obstacles in it and would be approximately spherical.
The sound waves are measured by their frequency and pitch.
