Which advantage occurs when accurately grinding lenses in Islamic Golden Age observatories used lenses with spherical aberration correction?

💡 Explanation

When spherical lenses are accurately ground, the refraction focuses disparate rays at slightly different points, correction aligns the focal points of rays passing through lens edges, improving sharpness. Therefore image sharpness is increased, rather than chromatic correction, angle widening, because aberrations uniquely influence focal precision.
