Causes of Chromatic Aberration?

Answer

Chromatic aberration is when the lenses are not able to focus all colors in the image. The main cause of chromatic aberration is because there is different index of refraction for different wavelengths of light in lenses. In the lens, when the waves of light decrease, the index of refraction then decreases.
