Question

What phenomenon causes the fuzzy image? What kind of lens is used to correct this, and how is it corrected?

Answer 1

In optics, chromatic aberration (abbreviated CA; also called chromatic distortion and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.[1] It occurs because lenses have different refractive indices for different wavelengths of light. The refractive index of transparent materials decreases with increasing wavelength in degrees unique to each.

Answer 2

Answer:

Chromatic aberration results in a fuzzy, unfocused image.

Chromatic aberration occurs when light of different wavelengths focuses at different points.

A converging lens helps light of different wavelengths focus at a common point
