# 02. Light as an environment

Editorial teaching text. Check scientific claims against the cited primary sources; the project framework is identified in the text.

Over a day, you move through home, streets, transport and work. The light changes at every stop. Seeing that sequence is useful before choosing a new lamp.

Light is electromagnetic radiation. In everyday life we encounter a whole system: the sun, windows, lamps, reflections, screens and our own position in a room.

The Academy considers a person in a specific place and time. The same lamp produces different conditions in different rooms. Light on a desk can differ substantially from light reaching the eyes.

## Key idea
Describe the source, space, time and person together.

## Human practice
Describe one real situation related to this topic. Separate observations from assumptions and list the evidence needed to check them.

## Agent assignment
Map the sources in one room. Record where the person sits, their viewing direction and their activity. Mark missing information explicitly.
