Light Sources



The visible spectrum is made of the colours we can see with the naked eye. Different colours of light have different frequencies.
Which color has the lowest frequency? The highest?

Slide 8 - Tekstslide

White Light



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

p. 32-37

Slide 9 - Tekstslide

How do we see colour?



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.
