Find the electric field amplitude at your ear

Reference no: EM13299191

Consider a cell phone that emits electromagnetic radiation with a frequency of 1.0 GHz and with a power of 70 W.

If your ear is only about 10 cm from the source of radiation, what is the electric field amplitude at your ear as you use the phone? Again assume the phone radiates as a point source.
