The Correct Option is A
Solution and Explanation
Let $a_1$ and $a_2$ be the amplitudes of the waves and intensities $I_1$ and $I_2$, then
$ \frac{I_1}{I_2} = \frac{a_1^2}{a_2^2} = \frac{16}{9}$
$\therefore \frac{a_1}{a_2} = \frac{4}{3}$
$ \frac{I_1}{I_2} = \frac{a_1^2}{a_2^2} = \frac{16}{9}$
$\therefore \frac{a_1}{a_2} = \frac{4}{3}$
