Additive and Subtractive Color Theory
The primary colors in additive color theory.
What are red, green, and blue?
A material that allows all light to pass through.
What is transparent?
The type of light produced by certain living organisms, like fireflies.
What is bioluminescence?
The bending of light as it passes from one medium to another.
What is refraction?
This part of the eye controls the amount of light that enters by adjusting the size of the pupil.
What is the iris?
The process of combining pigments in subtractive color theory.
What is subtractive color mixing?
When light is blocked by something opaque it forms this.
What is a shadow?
Glow sticks emit light through this chemical reaction.
What is chemiluminescence?
A mirror that caves inward and can focus light to a focal point.
What is a concave mirror?
The part of the eye responsible for focusing light onto the retina.
What is the lens?
This color is produced when all three additive primary colors are combined in equal amounts.
What is white?
This type of object allows some light to pass through but scatters it in different directions.
What is translucent?
This type of light source absorbs UV light and re-emits it slowly, causing a glow after the UV light is removed.
What is phosphorescence?
A mirror that is used in streets to see around corners because it has a wider view.
What is a convex mirror?
The light-sensitive layer at the back of the eye that converts light into electrical signals.
What is the retina?
The primary colors in subtractive color theory.
What are cyan, magenta, and yellow?
This property of light was shown through the making of periscopes.
What is 'light travels in a straight line'?
A light source that only emits light while receiving energy from another source, often used in highlighter pens.
What is fluorescence?
When light reflects off a rough surface and scatters in many directions.
What is diffused reflection?
The bundle of nerves that transmits visual information from the eye to the brain.
What is the optic nerve?
The color seen when an object absorbs all light wavelengths in the subtractive color model.
What is black?
These objects do not emit their own light.
What are non-luminous objects?
Where electric discharge is seen in nature and in cities.
What is lightning and Neon signs?
The name for the bending of light in a prism, causing a rainbow effect.
The light-sensitive cells lining the retina that help you see colour.
What are cones?
