Cell phone radiation has a wavelength of about \(300 \mathrm{~mm}\). You are in the lobby of an office building in which the façade is a series of large, multistory panes of glass separated by vertical aluminum beams installed every 500 \(\mathrm{mm}\) across the width of the building. Aluminum shields electromagnetic radiation. You are \(10 \mathrm{~m}\) from the glass trying to make a phone call, but you don't get any reception. Could this have to do with interference?
