Color Vision

The visible spectrum is

• Colours which make up white light (ROYGBIV)

• The amount of refraction that occurs when colour passes through a prism

• The splitting up of white light through a prism

• Also called a rainbow

This is _______________. The splitting up of white light into the colours of the spectrum

• Refraction

• ROYGBIV

• Visible spectrum

• Dispersion

This rainbow formed because

• Only the droplets highest in the sky refracted all colours to our eyes

• Sunlight was internally reflected from inside the droplets back to your eyes

• The visible spectrum was dispersed with the sun in front of the rainbow

• Only the droplets lowest in the sky refracted all colours to our eyes

When only 2 primary colours overlap, you get a _________________

• Visible specturm

• Secondary colour

• Absorbed colour

• Refracted colour

We can see this calculator as white because it ...

• Reflects all colours

• Reflects no colours

• Absorbs all colours

• Absorbs no colours

These shoes appear black because ....

• Reflects all colours of the spectrum

• Reflects no colours of the spectrum
