Two waves $X$ and $Y$ have equal frequency. The amplitude of $X$ is $1.5A_0$, while the amplitude of $Y$ is $2.5A_0$. They arrive at the same point and combine by superposition to produce a resultant wave. For this resultant wave, what is the ratio $\frac{\text{maximum possible intensity}}{\text{minimum possible intensity}}$?
- A1.7
