Expert Answer:



What is Chromatic Aberration?

In optics, chromatic aberration is caused by a lens having a different refractive index for different wavelengths of light (the dispersion of the lens).White light was composed of multiple wavelengths. Simple lenses will refract (bend) light differentially as a function of wavelength. Short (blue appearing) wavelengths are refracted more than long (red appearing) wavelengths. Consequently, lenses like the one shown above will not image light all in one place.
