Classifying Materials | Opaque Objects | Combining Colors | Reflection | Bending Light Rays |
---|---|---|---|---|
Transparent
A material that transmits most of the light making it see-through
|
reflects
In red light, an apple appears red because it (absorbs/reflects) red light.
|
Red, blue, green
What are the three primary colors of light?
|
Regular reflection & diffuse reflection
Two ways in which a surface can reflect light.
|
The light changes speed (slows down or speeds up)
What happens to light when it enters a new medium or material?
|
Opaque
A material that you are unable to see through.
|
absorbs
In blue light an apple will appear black because it (absorbs/reflects) blue light.
|
Magenta, cyan, yellow
Name the three primary colors of pigment.
|
Diffuse reflection
Parallel light rays hit an uneven, rough surface
|
Refracted
When white light enters a prism, each wavelength is ______.
|
translucent
A material that scatters the light so you see something blurred.
|
orange
You are wearing an orange hat outside in the sunlight. What color(s) of light does the hat reflect?
|
black
Which color is produced by mixing equal amounts of the primary colors of pigment?
|
Metal, glass, and calm water
Regular reflection is produced by which shiny surfaces?
|
Index of refraction
The measure of how much light bends
|
opaque
A material that reflects or absorbs all of the light that strikes it
|
Red, yellow, green, blue, violet.
You are wearing an orange hat outside in the sunlight. What color(s) of light does the hat absorb?
|
By combining equal amounts of the primary colors of light.
How is white light produced?
|
Regular reflection
Which kind of reflection produces an image, or exact copy of an object?
|
gas
Do solids, liquids, or gases cause the least change in direction of a light ray?
|
Transparent, translucent, opaque
The three classification of materials.
|
Reflected
The color of an opaque object is _______.
|
pigment
Inks, paints, and dye contain colored substances called ________.
|
The paper looks and feels smooth, but has small bumps that reflect light at different angles.
Why won't a piece of paper produce a mirrored reflection?
|
Red
Which color has the longest wavelength?
|
