White light falls on a thick lens. The red wavelength and the blue wavelength fall at different focuses. The lens is said to exhibit

Question

Quizplus · Accepted Answer

Chromatic aberration is the phenomenon where different wavelengths of light are refracted differently by the lens, causing the image to be blurred and/or colored. In this scenario, the red and blue wavelengths are not focused at the same point, indicating the presence of chromatic aberration. Hypermetropia and myopia refer to visual disorders and are not relevant to the optics of a lens. Astigmatism and spherical aberration are also aberrations of a lens, but they do not specifically refer to the issue of different wavelengths being refracted differently.
