Light

• What is Light?

• Where does it come from?

• How do we perceive (detect) it

• What is Light? Light is a form of radiation that makes up a relatively small part of the Electromagnetic Spectrum that many life forms on Earth can detect.

The Outline

• A tool for organizing a lot of information in a Logical framework.• It provides a structure that can be used as a

convenient roadmap to compose a paper, study a chapter in science, history or any subject for that matter.

• There are rules that dictate how to put an outline together:

General Outline Structure TITLE I. Topic #1

A. Subtopic or Important Fact #11. Detail #12. Detail #23. Detail #3

B. Subtopic or Important Fact #24. Detail #15. Detail #2
