Physics Themed: Unit 4 "Light & color"

04- Light & Color
Summary: In the last unit you learned about sound waves, now you learn about light waves and very interesting and useful phenomenon of light that you see every day. To fully understand about what we see, you have to understand about how our brains process images and the physiology of the human eye. We will learn about how your brain interprets colors, electromagnetic spectrum and the same wave equation applied to light, additive and subtractive color mixing, eye physiology, after images, why the sky is blue and sunsets are red, basics of LCDs, and about the concept of polarization of light.

Resources: Online book chapter 30, readings guide 30, reading packets 3, 4, work packet, handouts.
