What best describes radiant light according to Gibson?

The concept of radiant light, as defined by James J. Gibson, refers to light that is emitted from a light source. Gibson emphasized the ecological approach to perception, focusing on how light, specifically radiant light, plays a crucial role in the way organisms interact with their environment. This type of light is significant because it informs us about the properties of surfaces and objects in our surroundings, allowing for perceptual experiences related to depth, texture, and color.

Gibson's work highlighted the importance of the direct perception of light as it enters our eyes and shapes our understanding of the visual world. When we think about radiant light, it is inherently linked to its source and its role in illuminating an environment. This understanding sets the foundation for exploring how light affects perception in a practical ecological context. Thus, the description that it is light emitted from a source aligns perfectly with Gibson's theories on perception and its relationship with light in the context of human experience.
