What happens to white light when it passes through a prism?
The light is refracted the amount of refraction depends on wavelength, so different colors are refracted different amounts.
Light all speeds up in a prism so it comes out
White light is changed into colored light in the prism and comes out
The light is replaced in the prism with colored light

Blue
Red
Green
Yellow
A shadow is created by the....
absence of light.
absence of waves.
absence of color.
blocking of sound.

All the colors are being absorbed by the leaf.
What does it mean to see the color white?
Our brains receive too much information and can't put it together properly.
Our brains aren't receiving enough information, so they can't fill in the gaps in understanding properly.
Sunlight is special because it...
contains all the colors of the rainbow.
contains most of the colors of the rainbow.
contains white light and black light.
contains black light.
The sky is blue because...
blue is the color most scattered or reflected by our atmosphere.
red is the color most scattered or reflected by our atmosphere.
