Which optical consequence resulted from medieval Islamic scholars grinding spherical lens surfaces for astronomical instruments?

💡 Explanation

When using spherical lens surfaces, chromatic aberration occurs because different wavelengths of light refract at slightly different angles, leading to fringing, particularly noticeable in telescopes. Therefore chromatic aberration results, rather than enhanced clarity, brightness, or IR transmission which require different optical properties and lens designs.
