A point source surrounded by vacuum emits an electromagnetic wave of frequency of 900 kHz. If the power emitted by the source is 15 W, the amplitude of the electric field of the wave (in x10^(-3) V/m) at a distance 15 km from the source is: find the value x?? "("(1)/(4pi in_(0))=9xx10^(9)(Nm^(2))/(C^(2)) and speed of light in vacuum =3xx10^(8)ms^(-1) )
