Waves bounce back when they hit something solid or move to a different material.
Imagine throwing a ball at a wall. The way the ball hits the wall and then bounces back follows a rule called the Law of Reflection. This rule says that the angle at which the wave hits the barrier (the angle of incidence) is the same as the angle at which it bounces back (the angle of reflection). We can write this as .
Here are some things that affect how waves reflect:
Medium: Different materials (like air and water) affect how fast and at what angle the waves bounce back. For example, sound waves behave differently in the air than they do in water.
Surface Type: When waves hit rough surfaces, they scatter everywhere and bounce back in many directions. This is called diffuse reflection. On smooth surfaces, waves bounce back in a more organized way, which is known as specular reflection.
Angle of Incidence: The angle at which the wave hits a barrier can change how strong the bounce back is and how the wave behaves afterward.
Frequency and Wavelength: Waves with higher frequencies, like light, reflect differently than lower frequency waves, like sound. This happens because of how the waves interact with the material they're bouncing off.
Understanding how waves reflect is important in many areas. For example, it helps when designing spaces for music or creating devices that use light.
