Bank 2 is the the front row of engine cylinders.
Sensor 1 is likely to be seen looking straight down between the engine and radiator, mounting into the exhaust pipe.
Sensor 2 is further down the exhaust system, after, or "downstream" from the catalytic converter.
Bank 1, by the process of elimination of course is the row back by the firewall/windshield.

2 other terms you'll hear when talking about O2 sensors: Upstream and downstream.
These terms are in reference to the catalytic converter and the flow of the exhaust gases. So the sensor that is closest to the engine is upstream from the converter - and not surprisingly, the sensor after are downstream.
