The superposing waves are represented by the following equations $y_{1} = 5 sin 2 π (10 t - 0.1 x)$ , $y_{2} = 10 sin 2 π (20 t - 0.2 x)$ . Ratio of intensities $I_{ma x} / I_{min}$ will be:

Options:

Answer:

Solution:

The frequencies differ (10 and 20 Hz), so at a point the amplitudes combine between $10 - 5$ and $10 + 5$ . $I_{ma x} / I_{min} = (\frac{15}{5})^{2} = 9$ .
