What is the best model for scattered reflection from paper compared with a mirror?
What is the best model for scattered reflection from paper compared with a mirror?
Tap to reveal answer
Many reflected rays go in different directions from the paper. Rough surfaces scatter light in multiple directions, unlike smooth mirrors.

What happens in a model when an object blocks light from reaching your eye?
What happens in a model when an object blocks light from reaching your eye?
Tap to reveal answer
A shadow forms because light cannot reach the eye from that direction. Objects block light paths, creating dark areas where light can't reach.
