Unit 10 Continued
In Unit 10 we expanded more on light and rays. Today we learned about diffuse reflection also known as irregular reflection and a Regular/specular reflection. A diffuse reflection also known as irregular reflection is the rough or bumpy surface of an object. An example of diffuse reflection is a table top because table tops are not smooth, they are bumpy. A Regular/Specular reflection is when light comes in and bounces off or strikes back at you or an object depending on where you are. An example of a regular/specular reflection is a mirror because the surface of a mirror is flat and smooth. In the first picture at the top there is a faded rainbow. We learned today that rainbows are always the opposite of where the sun is sitting or where it sets. I thought that was cool. The second picture is of the bright blue sky. Many people think the sky is blue because it is a reflection of the ocean but it's because there is a scattering of lower frequency/wavelengths in the sky. The ocean is blue because it absorbs the lower wave lengths and lower light frequencies. The last picture is a picture of an experiment we did in class. We were observing different types of light behavior.

Nice explanation. Its short and simple, but it still explains the basic concepts of reflection and color mixing.
