Elaboration
- examples: brightness, colour
- objects are made visible by radiating their own light or being illuminated by reflected light
- interactions of light with different objects create images and shadows
- light interactions can make plants grow, make shadows, or cause sunburn, depending on the source and location (seasons depend on light from the sun and how spread out the sun’s rays are)
