What is reflection in terms of light behavior?

Reflection in terms of light behavior refers to the bouncing of light off a surface. When light encounters a reflective surface, such as a mirror or a calm body of water, it strikes the surface and reflects back into the medium from which it originated. This process follows the law of reflection, which states that the angle of incidence (the angle at which the incoming light hits the surface) is equal to the angle of reflection (the angle at which it bounces away).

Reflection is a critical concept in understanding how we perceive our environment, as it allows us to see images and colors on surfaces. The nature of the surface plays a significant role; smooth, shiny surfaces typically result in clear reflections, while rough surfaces scatter light, leading to a diffuse reflection.

The other options describe different phenomena related to light. Bending of light refers to refraction, where light changes direction due to a change in speed as it passes through different mediums. Changing speed of light pertains to how light travels through various materials, which can affect how it bends or refracts. Absorption of light involves the uptake of light energy by materials, which is not described as a bouncing action.
