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

How does the wavelength of orange light compare to the wavelength of blue light?

• They have the same wavelengths.

• Blue light has a longer wavelength than orange light

• Orange light has a longer wavelength than blue light.

• Orange light has a shorter wavelength than blue light.

Use the model to rank the colors of light from highest to lowest energy. yellow violet red green

Which of the following are limitations of the model? Select ALL correct answers.

• The model does not show the different shades of each color

• The model does not show how fast light moves

• You can use the model to compare frequencies for each color

• You can use the model to compare wavelengths for each color.
