Question

Content: Geometrie optics 1. The huge aquarium has walls made from the glass n = 1.5 and filled with water n = 1.33. At which angles the diver inside the aquarium must send the light that the light fully can be seen from outside by visitors.

I would be glad if you can provide some detailed explanation (like in order for the light to be seen outside what condition must be met)
