Properties of Light

Sunlight is a form of electromagnetic radiation, transmitted as waves or photons.

Sunlight is a mixture of all colors of light. Each color of light has a different wavelength, and thus a different amount of energy.

Plants only use visible wavelengths of light.

Blue light has more energy than red light (its faster for a small wave to move than a long wave----think of jumping rope!)

When an object reflects a color, that is the color it appears.

Blue book reflects blue. All other colors are absorbed.

Green leaf reflects ____?____. All other colors absorbed.
