We all know the trick of pretending to lose a cell phone connection, but the receiving person (in reality) can usually tell you have a good connection. This time, you are in luck- you are using a cell phone at 850 MHz, on one side of you is the cell phone tower, and on the other side, a tall building. 1) what is the wavelength of your cell phone transmission? 2) How far from the building should you stand to lose reception? 3) Since the phone companies employ good engineers, that trick won't actually work. However, you happen to see a chain-link fence nearby, and (out of desperation) try to use that as a diffraction grating to scatter the radiation. Estimating the link spacing as 5 cm, will this work?
