✋Introduction
How we see things
In this lesson: I can explain how we see objects around us using our eyes. Luminous objects give out light, non–luminous objects do not. All surfaces reflect light. Mirror–like surfaces reflect light in a regular way, other surfaces scatter light.
Lesson outcome
Waxaan sharxi karaa sida aan wax u aragno iyada oo la adeegsanayo indhaha.
