1. The separation of white light into its constituent colors is called .
2. A prism works by light, causing different wavelengths to bend at different angles.
1. Explain why a red apple appears red under white light and black under blue light.
2. Describe the difference between additive and subtractive color mixing, providing an example for each.
Observe the diagram below showing white light passing through a prism.

Based on the diagram, what is the order of colors from shortest to longest wavelength as they emerge from the prism?
