Answer:
here as we increase the distance the intensity will decrease and hence the amplitude of the electric field will decrease and vice-versa
Explanation:
As wee know that the amplitude of the wave will decide the energy of the wave
Here we know that energy density of electromagnetic wave is given as

now we have

so here we can say that intensity of the wave at the given distance from the source is given by formula

so here as we increase the distance the intensity will decrease and hence the amplitude of the electric field will decrease and vice-versa.
 
        
             
        
        
        
It’s 4 because a coiled springs is closely spaced then widen
        
                    
             
        
        
        
The CORRECT answer would be false. They are different and so therefore the answer is false. 
Hope this helped ‼️
