Sound is a series of compression waves that moves through air or other materials.These sound waves are created by the vibration of some object, like a radio loudspeaker. Creating sound Whenever an object in air vibrates,it causes compression waves in the air.These waves move away from the object as sound.There are many forms of the vibration,some not so obvious.Sound can also be created by vibrating an object in a liquid such as water or in a solid such as iron. A train rolling on a steel railroad track will create a sound wave that travels through the tracks.They will then vibrate,creating sound in air that you can hear,while the train may be a great distance away. ------------------------------------------ joycelorenza Influencer
