The presentation discusses light and lighting fixtures. It defines light and how it is produced through electrons moving between orbits in atoms. It then covers the different types of light sources including natural light and various artificial lights. The rest of the presentation focuses on methods of lighting, including types of lighting fixtures for indoor and outdoor use. It also addresses the effects of lighting in different areas and the advantages and disadvantages of natural versus artificial light.

7. What is light?
Light is electromagnetic radiation of
a wavelength that is visible to the
human eye (in a range from about
380 or 400 nanometres to about
760 or 780 nm). In physics, the term
light sometimes refers to
electromagnetic radiation of any
wavelength, whether visible or not.

8. How light is produced?
Electrons get
kicked into a
different orbit
This doesn’t
happen very often
in solar
systems, but it
does in atoms
If you add energy
to an atom (heat it
up), the electrons
will jump to bigger
orbits.
When atom
cools, electrons
jump back to
original orbits.
As they jump

back, they emit
