The underlined colors in number two are the primary colors of light. We used an old color addition box to show how the primary colors add to make other colors, but you can get the same information here. Note that white and black are not really "colors" in physics because they do not have a designated wavelength - white is all colors and black is no light at all.
We also talked about how screens on devices like televisions and cell phones use RGB pixels to make different colors. You can read about that here.
Then we switched to the other lesson, which was kicked off by number three in bellwork. It would be a good idea to read about stereoscopic vision here. We moved on to polarizers and demonstrated how the difference between unpolarized light an polarized light as well as how polarizers function with some springs and golf clubs. You can read about polarization in the intro to the Wikipedia page.
We then we talked about ways we use polarizers or polarized light. There are lots of examples later in the Wikipedia page, but we focused on polarized sunglasses and 3D movies. The 3D movies are explained in the second paragraph of the Display Technologies section.
Your homework tonight is a light waves practice worksheet that Ms. Trinkley gave me before the printers broke. Please put your answers on the back.
