Fun with Filters

Posted in Science

We have been investigating what happens when we put different coloured filters over different colours. The visible light spectrum has red, orange, yellow, green, blue, indigo and violet. If you look at white light through a red filter, the red filter absorbs orange, yellow, green blue, indigo and violet.

We also had fun looking through rainbow glasses!

Can you explain more of the science behind this investigation? Can you remember how rainbows are made?
