When white light from the sun passes through a prism, it is broken down into bands of light that form colors. The wavelength, , (in nanometers) of some common colors are: Blue:
Green:
Yellow:
Orange:
Red:
When a fireworks display made of copper is burned, it lets out light with wavelengths,
, that satisfy the relationship
. Write this inequality without absolute values; find the range of possible values for
. Using the preceding list of wavelengths, determine the color of that copper fireworks display.
