Light Basics and Geometrical Optics
previous page

 

This text is meant to accompany class discussions. It is not everything there is to know about uniform circular motion. It is meant as a  prep for class. More detailed notes and examples are given in the class notes, presentations, and demonstrations. See the links below.
 

Geometrical optics is about modeling the behavior of light as a particle. But we can also model light as a wave.

 

Wave review

Recall that

wave equation

"c" is the wave speed in [m/s]
"λ," (the Greek letter "labmda,") is the wavelength in meters, [m].
"F" is the frequency in Hertz, [Hz.]

 

At the nodes, nothing moves. The antinodes, occur at the amplitude.

Diffraction

 

This video from Bozeman science will describe some key concepts about diffraction. Incuding what it is and when it occurs.
