Which problem arose when early Islamic astronomers used geometric optics principles on astrolabes with highly reflective metal surfaces?

💡 Explanation

Inaccurate angular readings resulted because the *specular reflection* of the sun caused difficulty precisely aligning the astrolabe, therefore observers had issues, rather than material fatigue or alignment difficulties due to metal oxidation without intense solar glare.
