|Does light travel in waves?|
Thomas Young's double slit experiment demonstrates that light is a wave phenomenon.
As the waves pass throught the slits they fan out and interfere with each other to produce the pattern on the screen.
This patterns reveals constructive and destructive intereference.
of Electromagnetic Waves.
The Electric and Magnetic Fields move perpendicular to the propagation of the wave.

|How are Electromagnetic Waves Generated?|
|Electrons moving from one orbit to another release photons of light. (electromagnetic radiation)|
|Interaction of Electromagnetic Radiation and Matter|
This is what the universe is all about.
|Reflection and Refraction|
|White Light is composed of many different frequencies.
When passed through a prism, these frequencies are diffracted at different angles.
