Light
Is a form of energy that travels in waves
Unlike sound, light does not need molecules to help it spread.

Allows people and animals to see things.

Slide 15 - Slide

Visible spectrum
All the colors we can see with the naked eye.
Different colors of light have different frequencies.
Which color has the lowest frequency? The highest?

Slide 16 - Slide

White light
White light is made of all the colors of the visible spectrum.
We can split white light into its colors by using a prism.

Slide 17 - Slide

How do we see color?
The human eye sees color when light bounces (reflects) off an object and goes into our eye. The color of light that gets reflected is the color that we see.  

All other colors of light get 
absorbed by the object so that 
we don’t see them.

Slide 18 - Slide

Seeing black and white

White objects reflect all the colors 
which together make the color white.

Black objects absorb all the colors 
so there is nothing left to see.

Slide 19 - Slide

Colored light
Different colors of light can have an effect on what color an object appears to be.
