← HistoryWhich astronomical calculation was significantly simplified using the 'universal plate' on an astrolabe?
A)Determining the user's latitude
B)Calculating planetary conjunctions
C)Predicting lunar eclipses
D)Finding prayer times at any latitude✓
💡 Explanation
When a universal plate is used, stereographic projection simplifies calculations of altitude and azimuth for any latitude because the plate is not limited like regular astrolabes. Therefore prayer times can be determined more easily, rather than only latitude which uses other observations, or planetary/lunar eventsrequiring complex epicycles.
