What is the angular width of the electromagnetic wave

Reference no: EM13523125

You need to use your cell phone, which broadcasts an 828 MHz signal, but you're in an alley between two massive, radio-wave-absorbing buildings that have only a 14 m space between them.

What is the angular width, in degrees, of the electromagnetic wave after it emerges from between the buildings?
