Answer:
Explanation:
From the question we are told that
Distance b/e antenna's 
Frequency of antenna Radiation
Distance from receiver 
Intensity of Receiver 
Distance difference of the receiver b/w antenna's 
Generally the equation for Phase difference 
is mathematically given by
<h3>
</h3>
Therefore phase difference f between the two radio waves produced by this path difference is given as
