Step 1: Understand what a wave is. A wave is a disturbance that travels through a medium (like air, water, or solids).
Step 2: Learn about different types of waves. There are two main types: longitudinal waves and transverse waves.
Step 3: Know what a longitudinal wave is. In a longitudinal wave, the particles of the medium move back and forth in the same direction as the wave travels.
Step 4: Identify sound waves. Sound waves are created when something vibrates, causing the air particles around it to move.
Step 5: Connect sound waves to longitudinal waves. Since the air particles move in the same direction as the sound wave travels, sound waves are classified as longitudinal waves.
