The phenomenon of light returning after hitting a smooth surface is called reflection of light, which corresponds to option [B]. Reflection occurs when light rays strike a smooth, shiny surface and bounce back into the medium from which they originated. This process follows the law of reflection, which states that the angle of incidence (the angle at which the incoming light ray hits the surface) is equal to the angle of reflection (the angle at which the light ray leaves the surface). Common examples of reflection include the way we see our image in a mirror or the way light glints off a calm body of water. Reflection is a fundamental concept in optics and is crucial for various applications, such as designing optical instruments, creating reflective surfaces in architecture, and even in everyday activities like using a periscope or applying makeup. The precise and predictable nature of light reflection allows it to be harnessed effectively in both scientific and practical contexts.
