Chapter 32, Problem 28E
You’re inside a metal building that blocks radio waves, but you’re trying to make a call with your cell phone, which broadcasts at a frequency of 950MHz. Down the hall from you is a narrow window measuring 35 cm wide. What's the horizontal angular width of the beam (i.e., the angle between the first minima) from your phone as it emerges from the window?
