question:
After losing a contest to this character, Heracles briefly joined the Thiasus, his retinue. Some stories claim he was the son of Persephone and that, at Heras bidding, the Titans ate all of him but his heart, which Zeus put in the womb of his better-known mother. He is sometimes said to be the father of the Graces with Aphrodite, and he fathered Oenopion with Ariadne. Acoetes, the helmsman, was the only one spared when pirates attempted to sell this god into slavery, and he once drove his cousin Pentheus mad, luring him out into the woods where his Maenads tore him apart. For 10 points, identify this son of Semele, the Greek god of inspired madness and wine.

One description of the court of this leader is a History written in Greek by Priscus of Panium. A policy of appeasement was unsuccessfully used by Theodosius II to try and stop this ruler from invading his empire. This man fought a battle against forces under Theodoric I and Aetius on the Catalaunian Plains.

For 10 points, name this ruler who gained the title ""Scourge of God"" for his invasions into the Roman Empire while leader of the Huns.
answer:
History

question:
The radiation per unit solid angle of a wave undergoing this process varies with the cosine of the angle between the line of sight and the perpendicular. Lambert's emission law applies to the directionally independent form of this process, in which a microscopically rough interface causes it to occur in many different angles in the "diffuse" type of this phenomenon. The "specular" variety of this process is modeled by a law which states that the angle of incidence equals this process's namesake angle. For 10 points, name this optical phenomenon in which a wavefront rebounds off of a surface, often facilitated by mirrors.

Science
