Which optical distortion arises in early refracting telescopes due to simple lens curvature limitations regarding light dispersion?

💡 Explanation

When light passes through a simple lens, chromatic aberration occurs because different wavelengths are refracted differently, resulting in colored fringes around the image. Therefore colored fringes result, rather than blurry image, or other off-axis distortions which require aspherical lens imperfections.
