What do you know about color?

In this section you are asked some questions to get you thinking about color. You are only graded on putting forth an effort to answer the questions in this section. The purpose of this is to compare what you know before and after going through the activity.

Be sure to go through the entire PowerPoint presentation on the assignment page so that you get the instructions for each activity.

Please type answers after each question in a color that is easy to read and differentiate from the instructional text.

Activity 1 - Color Mixing

This activity can be done one of three ways:

• Using the three different primary color lights and shining them on to a white surface. LED lights work the best because they are monochromatic (single wavelength) Watch the first 4 videos listed on the Exploratorium Video Demonstrationhttps://www.exploratorium.edu/snacks/colored-shadows?media=7604
• Research color addition at The Physics Classroomhttp://www.physicsclassroom.com/class/light/Lesson-2/Color-Addition
• Using the custom color function on this Google Document. When you go to define a custom color, you can choose them, but you can also put in the code. Here is how the code works:
