Reflection of Sound Waves
Quick fact
Sound can reflect off surfaces just like light, creating echoes that help us navigate and communicate.
Why this is interesting
Have you ever heard an echo in a cave? It’s not magic—it’s the reflection of sound waves bouncing back to your ears.

Understanding Reflection of Sound Waves
When sound waves hit a surface, they can bounce back instead of passing through. This is called reflection. Imagine throwing a ball at a wall—it bounces back. Sound does something similar when it hits a solid or liquid boundary.
A deeper explanation
Reflection occurs when sound waves encounter a change in the medium they are traveling through, such as air to a wall. The waves bounce back into the original medium, creating an echo. This phenomenon is governed by the law of reflection: the angle at which the wave hits the surface equals the angle it bounces off. Reflection helps explain how we hear echoes and how sound behaves in different environments.
