What are the three additive colors?

Red, Green, Blue

What are the three subtractive colors?

Cyan, Magenta, Yellow

Using two or more lights (of colors you decide), tell how the make the following colors:

Green – Can’t make red, green or blue with additive colors – you will always end up with more than just green

Magenta – red and blue

Using colored filters in front of one white light, tell how to make the following colors:

Cyan – Can’t make cyan, magenta, or yellow with subtractive colors – if you use two filter, you have subtracted at least two colors and can’t have magenta, yellow, or cyan as these all need two colors

Red (you can’t use a red filter for this) – Magenta (-G) and Yellow (-B)

Green (you can’t use a green filter for this) – Yellow (-B) and Cyan (-R)

Black – Red & Green, Red & Blue, Green & Blue, Red + Cyan, Green & Magenta, Blue & Yellow

What color does a green shirt appear when a blue light shines on it?

Blue light (-R & -G) and green shirt (-R & -B) = Black

What color does a green shirt appear when a magenta light shines on it?

Magenta light (-G) and green shirt (-B & -R) = Black

What color does a red shirt appear when a magenta light shines on it?

Magenta light (-G) and red shirt (-B & -G) = Red

What color does a black table appear when a cyan light shines on it?

Cyan light (-R) and black table (-R, -B, & -G) = Black

What is the complementary color of green? Why?

Magenta because it has Red and Blue. When Red and Blue and Green shine together, the result is white

What is the complementary color of magenta? Why?

Green. Magenta is Red and Blue. When Red and Blue and Green shine together, the result is white

What type of wave are electromagnetic waves?

Transverse

List the electromagnetic spectrum from highest to lowest frequency. Gamma rays, X-rays, Ultraviolet, Visible Light, Infrared, Microwaves, Radio waves

List the colors of visible light from shortest to longest wavelength.

Violet, Indigo, Blue, Green, Yellow, Orange, Red

What color has the most energy?

Violet because it has the highest frequency

What part of the electromagnetic spectrum has the most energy?

Gamma rays because they have the highest frequency
