Bring a large pot of water to just to a boil. You want enough water to comfortably hold all the shrimp. There should be about 1 to 2 inches (2.5 to 5.1 cm) more water than there is shrimp.
The amount depends on the type of mineral. A large group of minerals  the opaque minerals  do not transmit significant light, even in thin section. These minerals do, however , reflect light back that can tell us a great deal about their identity and origin. These minerals typically have significant metallic bonding (e.g., native elements, sulfides, oxides).
32) Light refracts when traveling from air into glass because light A) has greater intensity in air than in glass. B) has greater intensity in glass than in air. C) has greater frequency in air than in glass. D) has greater frequency in glass than in air. E) travels slower in glass than in air.
