The intensity increases 16 times.

The relationship between intensity and amplitude is given below:

<span>   I = constant A^{2}

Since, A becomes 4 times, A' = 4A</span><span>
Thus the intensity becomes, I' = constant </span>× (<span>4A)</span>²<span> 
                                              
                                         </span>⇒<span> I' = 16A</span>²

Therefore, the intensity of the wave is increased by 16 times
