• Red, Green, Blue

• Magenta, Yellow, Cyan

• White & Black

• None of these

White light is composed of what?

• All frequencies of the rainbow.

• White light frequencies.

• The frequencies of red, orange and yellow.

• The frequencies of blue, indigo and violet.

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

Which colour light is being reflected?

• Magenta

• Red + Blue

• Orange

• All colours except for orange

What does ROYGBIV stand for in the context of the visible spectrum?

• Green

• Violet

What phenomenon causes the separation of white light into the ROYGBIV spectrum?

• Diffraction

• Reflection

• Refraction
