How is a chromatic AbeHow is a chromatic aberration related to a prism spectrograph?

chromatic aberration is due to the change in n, which is a function of the wavelength. different wavelength--> different n--> different refraction-->different angle-->this is spectrograph.

With Chromatic aberration, light is reflected through glass, shorter wavelengths bend more than longer wavelengths. With the prism spectrograph (Newton), violet (short-wavelength) light bends most,...

The distortion of light through a camera lens, seen to greatest effect in the parts of the image with the greatest amount of contrast.

spherical aberration can corrected by using spherical lenses such as the planoconvex lens and chromatic aberration can also be corrected by using the achromatic doublet ie the flint and glass crown.

not totally, chromatic aberrations can be minimized by the use of filers (usually blue); or by lenses corrrected red, blue, and other wavelengths, called apochromatic lenses. The most loogical, but...
