Front

What determines the color of a pigment?

Back

The wavelength of light it reflects and the wavelength of light it absorbs.

Front

What is the phenomenon called when light waves bounce off an object?

Back

Reflection.

What is the visible spectrum?

Back

The range of wavelengths of light that can be seen by the human eye, typically from about 380 nm to 750 nm.

Front

What is refraction?

Back

The bending of light as it passes from one medium to another.

Front

What is absorption in terms of light?

Back

The process by which an object takes in light energy and converts it to other forms of energy.

Front

What color does an object appear if it reflects all wavelengths of light?

Back

White.
