Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following colors has the shortest wavelength in the visible light spectrum?
Red
Green
Blue
Violet
2. What happens when white light passes through a prism?
It is absorbed by the prism.
It is refracted and separated into its component colors.
It is reflected back as white light.
It changes frequency.
3. The primary colors of light are , , and . When mixed together in equal proportions, they produce light.
4. An object appears red because it red light and all other colors of the visible spectrum.
5. Black objects absorb all wavelengths of visible light.
True
False
6. The color of light is determined by its amplitude.
True
False
7. Explain the difference between additive and subtractive color mixing. Give an example of where each is used.
Observe the diagram below showing white light passing through a prism.
8. Based on the diagram, describe what happens to white light when it passes through a prism, and list the colors of the visible spectrum in order from longest wavelength to shortest wavelength.
