Answer:

\sqrt{18} :7

Explanation:

I=A^{2} \cos ^{2} \frac{\Delta \phi}{2}

\begin{aligned}&I \propto A^{2} \\&A \propto \sqrt{I}\end{aligned}

\frac{I_{1}}{I_{2}}=\frac{A_{1}^{2}}{A_{2}{ }^{2}}

\frac{I_{1}}{I_{2}}=\frac{18}{49}

\frac{A_{1}}{A_{2}}=\sqrt{\frac{I_{1}}{I_{2}}}=\sqrt{\frac{18}{49}}

\frac{A_{1}}{A_{2}}=\frac{\sqrt{18} }{7}
