Post #24 - Reflection

Today in class we learned about the law of reflection. The angle of incidence = angle of reflection. This means that the angle a light source hits a mirror, the angle of reflection will be the same. There are two types of reflections. The first one is specular reflection which means the reflection is off a smooth surface. The other reflection is diffuse reflection which means the reflection is off a bumpy surface so the reflection is all over the place. All angles are relative to the normal. The lab we did today helped us see specular reflection with a regular flat mirror and diffuse reflection with a curved mirror.
We also learned about colors and how mixing colors is different from mixing paint. The primary colors are red, blue, and green. Red + blue = magenta. Red + green = yellow. Blue + green
 = cyan. Red + blue + green = white. I learned that the sky isn't blue because of the reflection of the ocean but because the scattering of wave lengths in the upper atmosphere due to nitrogen.
