Chromatic aberration is caused by: a. imperfect shape of lens b. different refraction of the light spectrum c. uneven reflection of light colors d. uneven filtering of various colors

The correct answer is B. Chromatic aberration is caused by different refraction of the light spectrum.

Explanation:

Chromatic aberration is a phenomenon caused by the diffraction of light. The smaller wavelengths of the spectrum are refracted in the lens more than the higher wavelengths of the spectrum. The refraction of light depends on the refractive index of the lens. Again, the refractive index depends on the wavelength of light, which results in different wavelengths refracting at different angles, thereby detecting color aberration. Generally speaking, blue light refracts more than red light.

As a result of different color refraction, several objects of different colors are formed behind a lens in a slightly different location. Color aberration is utilized especially when it is desired to form a spectrum of an object. However, this is a serious problem if you want to get the most accurate pictures of your subjects. The problem can be corrected with a so-called achromatic lens.
