Why do we see a blue sky?
 * 1) Describe how reflection allows you to see things.
 * 2) What is the law of reflection?
 * 3) Draw an explanation of the law of reflection. Label the incident beam, angle of incidence, normal, reflected beam and angle of reflection.
 * 4) What is the difference between regular reflection and diffuse reflection?
 * 5) why can you see your image in a mirror but not in a wall?
 * 6) What is the difference between luminous and illuminated objects?
 * 7) What is absorption?
 * 8) Explain how absorption affects a beam of light.
 * 9) Describe an example of scattered light.
 * 10) How does refraction cause optical illusions (e.g. objects appearing to be different than they actually are)?
 * 11) How does refraction cause white light to be separated into to different colors when it passes through a prism.
 * 12) How is the amount of diffraction of light determined?
 * 13) Describe the affects of constructive and destructive interference of light.

 * 17) Explain why mixing of colors of light is called color addtion.
 * 18) What are the primary colors of light?
 * 19) What is a pigment?
 * 20) Describe why mixing of colors of pigment is called color subtraction.
 * 21) What are the primary colors of pigments.

 * What color of light will you produce if you mix green light with magenta light? Why?
 * How is that yellow color produced on a television screen?
 * Why are red, green, and blue called the primary colors of light?
 * What colors of light are reflected by an opaque black object?
 * What happens to the colors of light that are not transmitted through a transparent object?
