Reflection is the bouncing back of waves when they encounter a surface or boundary. When a wave encounters a reflective surface, it changes direction and returns to the original medium. This phenomenon is widely observed in daily life. For example, when we look into a mirror, light waves from our face are reflected off the mirror's surface and into our eyes, allowing us to see our reflection. Reflection is also utilised in various optical devices such as telescopes, periscopes, and retroreflectors. Moreover, it plays a crucial role in the functioning of radar systems and ultrasound imaging.
