Slide 15 - Tekstslide
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 - Tekstslide
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 - Tekstslide
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 - Tekstslide
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 - Tekstslide
Colored light
Different colors of light can have an effect on what color an object appears to be.
