Here's a breakdown:
* Wave: A disturbance that travels through a medium or space, transferring energy.
* Reflection: The process where a wave encounters a boundary and bounces back.
Examples of Reflection:
* Light: When light strikes a mirror, it reflects back, allowing us to see our image.
* Sound: Echoes are a result of sound waves reflecting off surfaces.
* Water waves: Waves in a pond or ocean bounce off obstacles like rocks or the shore.
The angle at which the wave hits the surface (the angle of incidence) is equal to the angle at which it bounces off (the angle of reflection). This is known as the law of reflection.
