Each wavelength of light has a unique interference pattern given by the equation above. Thus all the wavelengths

(i.e. colors) have a unique∆ybased on the equation given at the end of Example 1. This is how white light

separates out into its individual wavelengths producing a rainbow after going through a diffraction grating.
