The sky is blue because its component particles scatter -----

High-frequency light

Red + blue =

Magenta

If a material absorbs light of the most visible frequencies & reflects red, what color do you see?

Red

The color of a ----- object is the color of the light it transmits

Transparent

True/False: Different materials have different natural frequencies for absorbing and emitting radiation.

True

Pigment

Water is greenish-blue because it absorbs -----

Red

The color of opaque objects are that color because they do what with light?

Reflect

Spectrum

Magenta, yellow, and cyan are -----

Subtractive primary colors

Sunlight

What is black?

The absence of light

Black

The color spectrum goes: red, orange, yellow, green, -----, indigo, violet. What color is missing?

Blue

The color of an ----- object is the color of light it reflects

Opaque

Red, blue, and green light. These colors when added together produce white light.

Additive primary colors

A ----- emits a light that is deficient in high frequencies, so it reflects yellow light

Candle

Cells that contain ----- absorb light of most frequencies & reflect the green part so they appear green.

Chlorophyll

Every color has a ----- color that when added to it will produce white

Complementary

These colors added together will produce whote

Complementary colors

A ----- lamp is richer in higher-frequencies

Fluorescent

An ----- lamp emits light of all the frequencies but more of lower-frequencies

Incandescent

Who was the first person to form a systematic study of color?

Isaac Newton

Are black and white real colors?

No

Can the human eye see the highest frequency of light?

No

Can the human eye see the lowest frequency of light?

No

True/False: Newton showed that the colors in the spectrum were a property not of the prism, but of white light itself.

True

True/False: Strictly speaking, white isn't a color but a combination of all colors.
