Read each question carefully and provide the best answer. Show all your work for calculations.
1. Which phenomenon is responsible for the separation of white light into its constituent colors when passing through a prism?
Reflection
Diffraction
Dispersion
Interference
2. The primary colors of light (additive primary colors) are:
Red, Yellow, Blue
Red, Green, Blue
Cyan, Magenta, Yellow
Orange, Green, Violet
3. The electromagnetic spectrum ranges from long wavelength radio waves to short wavelength rays.
4. When all colors of the visible spectrum are combined, they produce light.
5. The color of an opaque object is determined by the colors of light it .
6. Describe the difference between additive and subtractive color mixing. Provide an example for each.
7. Explain why the sky appears blue during the day and red/orange during sunrise/sunset.
8. Observe the diagram below showing light passing through a prism. Label the colors of the spectrum in the correct order and explain why they separate.
