Have you ever wondered how you can hear music or the sound of your friend’s voice? It’s all because of something called a sound wave. But what exactly is a sound wave?
A sound wave is like a ripple in water, but instead of traveling through water, it moves through the air. Imagine you drop a pebble into a pond. The pebble creates ripples that spread out in circles. In a similar way, when something makes a noise—like clapping your hands—the sound creates waves that spread out in all directions through the air.
These waves are made up of tiny particles in the air that bump into each other, like a game of tag. When the particles get pushed together, they create areas called compressions. When they spread apart, they create areas called rarefactions. The compressions and rarefactions move through the air, carrying the sound to your ears.
Your ears are amazing! They catch these sound waves and turn them into signals that your brain can understand. That’s how you hear different sounds, like your favorite song or your teacher’s voice in class.
Sound waves can travel through other things too, like water or even solid objects. That’s why you can hear underwater or why you can hear a train coming if you put your ear to the tracks.
