Which outcome occurs when medieval astrolabes were subjected directly to intense, unfiltered sunlight?

💡 Explanation

Intense sunlight caused alteration of brass reflectivity, because *optical degradation* occurred due to incident photons. The brass alloy microscopically changes; therefore the reflection changes unexpectedly, rather than enhancing coordinate readings predicted by astrolabe geometry.
