Daily Reflection Prompt: Write 3 questions that you have about electromagnatic waves.

Transparent Materials Transparent material trans_____ most of the light that strike it. mit

Translucent Materials A translucent material sca____ light as it passes through, just as smoke, fog, and clouds scatter light as it passes through the air. tters

Opaque Materials An opaque material refl_____ or absorbs all of the light that strikes it. ects

Why does the apple appear red? Because the red light reflect it. All other light are absorbed.

What do you notice about the apple when it is shown in red light?

What do you notice about the apple when it is shown in green light?

What do you notice about the apple when it is shown in blue light?

What are the three primary colors of light? Red, Blue, Green

What are the three primary colors of pigment? Yellow, Magenta, Cyan What color do you get when you combine the three primary colors of pigment?

Why do three primary colors of pigments produce black instead of white? As pigments are added together, fewer colors of light are reflected and more are absorbed
