The conclusion of a sound argument Group of answer choices will always be true

<h3>What is  sound?</h3>

Sound is defined in physics as a vibration that travels as an acoustic wave through a transmission medium such as a gas, liquid, or solid. Sound is the reception of such waves and their perception by the brain in human physiology and psychology.

Sound is a form of energy produced by vibrations. When an object vibrates, the surrounding air molecules move. These molecules collide with molecules nearby, causing them to vibrate as well. This causes them to collide with more nearby air molecules.

When something vibrates, it sends waves of energy (vibration) into our ears, which produces sound. The vibrations travel to the ear via the air or another medium (solid, liquid, or gas).
