A digital cell phone emits 0.60Wattsof 1.9GHz= 1.9×109Hzradio waves. (Assume thewaves are passing through air so that their speed is effectively the vacuum speed of light). At a distance of10cm= 0.1mfrom the cell phone, (a.) What is the amplitude of the electric field? (b.) What is the amplitude of the magnetic field? (c.)What is the wavelength? (d.) Considering what you know (intensity, frequency, wavelength), etc. about these EM waves emitted by thecell phone, do you think the EM waves radiating from your phone are capable of causing bodily harm toa cell phone user?
