Visible Light and Color

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

• infrared

Evelyn is studying physics and needs to identify the colors included in the visible spectrum for her project. Which of the following sets correctly lists these colors?

• Red, Orange, Yellow, Green, Blue, Indigo, Violet

• Red, Blue, Green, Yellow

• Orange, Pink, Black, White

• Cyan, Magenta, Yellow, Black

______________ light is light the human eye can see.

• Ultraviolet

• X-ray

• Gamma

• Visible

The visible spectrum of light is made up of the colors we can see: red, orange, yellow, green, blue, and violet (ROYGBV). Each color can be determined by its unique amount of energy, wavelength, or frequency. The diagram below is a model of different colors of light in the visible spectrum. As you move down from red to violet, the crests of the waves get closer together.

Which of the following colors of light has the lowest frequency?

• red

• green

• orange

• yellow

This piggy bank appears as the colour it is because....

• Blue and green light is being absorbed into your eyes

• Blue and yellow light is being absorbed into your eyes

• Blue light is being reflected into your eyes

• Blue and green light is being reflected into your eyes
