The distance is
The amplitude of the electric field is
Generally the average intensity of the electromagnetic field from the radio transmitter is mathematically represented as
Here c is the speed of light with value
is the permeability of free space with value
So
=>
Generally this intensity can also be mathematically represented as
=>
=>
=>
The answer is B because, the farther the goes the speed starts to decrease and stops it depends on the frequency of the wave.
