- Photon: the smallest bit of light.
- Photoreceptor: the special type of cell in your eye that picks up photons and then signals the brain. They are located in the retina (a layer at the back of the eye). There are two types, rods and cones.
- Prism: a crystal object, such as cut glass, with at least three similar sides... more
- Retina: getting its name from the Latin meaning "net", the retina is located at the back of the eye and is where light is detected... more
- Wavelength: a property of photons that determines their energy (how "strong" they are).We see photons of different wavelengths as different colors.
Flashcard facts and information about how we see color
Biology Bits stories are a great way for you to learn about biology a little bit at a time. We’ve broken down information into pieces that are very tiny—bite-sized biology cards. Cutting out the cards will let you organize them however you want, or use them as flashcards while you read.
This set of bits will teach you about one of the ways we get information from the world around us: by seeing color. To learn more about the science behind your vision, visit Seeing Color.
