Colour : joining the colours back together Remember how you dispersed white light to give a spectrum of colours? Now do the opposite to it - you’ll need 2 prisms! A similar effect can also be seen using a colour wheel [or Newton’s disc].
Red objects Why does a red snooker ball look red in white light? Remember white light is made of a spectrum of colours. The snooker ball absorbs all the colours of the spectrum EXCEPT red, so red light is reflected into our eye. The snooker ball appears red.
But why do colours look different in different coloured light? Lets start with the example of a red ball in red light. The red light shines on the ball. The red ball reflects red light and so appears red.
