So, as I was sitting at my computer, trying to figure out what to write for this week's entry, I happened to notice that the screen of the Mac computer was acting like a mirror. I could see the part of my house that was to my left. The incident ray of light bounced off the computer screen, and the reflected ray traveled to my eye, allowing me to see the image in the picture. The image appears as far back as the actual scene is from the computer screen. The image is also actually behind the "mirror", as we learned in class. As you can tell, I'm kind of running out of things to write about...

In the picture, the yellow egg that Madi is holding appears yellow because the red and green cones in our eyes are stimulated. Since the sunlight is made up of red, blue, and green light, to appear yellow, only the blue light is absorbed while the red and green light is reflected. At Easter, I also remember that my cousin put his egg in every single color of dye, and it turned a really disgusting brown. Thanks to physics, I now know that mixing paint colors and light colors are different. In that lab we did, when we combined all the colors, the paint also turned an equally gross-looking brown. Only if you mix magenta, cyan, and yellow LIGHT together, will it produce black.
