 * __Light or Wave?__**
 * Newton discovered it as a particle
 * Interferes with other matter (electrons)
 * Huygen discovered it was a wave
 * Reflects
 * Refracts
 * Difracts

[|This is a really good website that shows reflection and diffraction.]

__**Here are some real examples done in class**__
 * Color Addition - The green red and blue light come together through the lens to make white light

 * Color Separation - The white light goes into the prism and separates due to the different wavelengths of the different colors

 * Refraction - The light bends when goes into the block as well as when it comes out of the block

 * Total Internal Reflection - When light reaches the critical angle of the medium it reflects
