Chapter 32, Problem 32.2DQ
When driving on the upper level of the Bay Bridge, west-bound from Oakland to San Francisco, you can easily pick up a number of radio stations on your car radio. But when driving cast-bound on the lower level of the bridge, which has steel girders on either side to support the upper level, the radio reception is much worse. Why is there a difference?

High microwave intensities can cause biological damage through heating of tissue; a particular concern is cataract formation. The U.S. Food and Drug Administration limits microwave radiation near the door of a microwave oven to 5.0 mW/m2. The window in a particular oven door measures 40 cm by 17 cm and is covered with a metal screen to block microwaves. Assuming power leaks uniformly through the window area, what percent of the oven’s 900-W microwave power can leak without exceeding the FDA standards?
