Okay kiddo, have you ever heard a sound like a dog barking, a bird chirping, or a music playing on your favorite superhero's movies? That sound you are hearing is called sound waves. Sound waves are like the invisible hands that move through the air and make us hear different sounds.
Now, different things in the world, like the air you breathe, the water you drink or the metal your bicycle is made of, let sound waves move through them at different speeds. In science, we call this the speed of sound.
Every element, which basically means different types of materials, have their own speed of sound. For example, the speed of sound of air is around 343 meters per second. This means that sound waves take 343 meters to travel through the air in one second.
But, the speed of sound in other elements is different. For example, the speed of sound in water is around 1500 meters per second. This means that sound waves can travel nearly 4 times faster in water than in air.
Similarly, the speed of sound in other elements such as metal, glass, or rubber is also different. This is because each element has its own unique properties, and sound waves move faster or slower depending on how the molecules in the element vibrate and interact with each other.
So, in summary, every element has a different speed of sound, which means that sound waves travel faster or slower depending on the material they are moving through.
