The superposing waves are represented by the following equations:
$y_1 = 5 \sin 2 \pi (10 t - 0.1 x)$ , $y_2 = 10 \sin 2 \pi (20 t - 0.2 x)$ Ratio of intensities $\frac{I_{\max}}{I_{\min}}$ will be
Text Solution
Verified by ExpertsThe correct answer is:
B
$a_1 = 5, a_2 = 10$ 
$\frac{I_{\max}}{I_{\min}} = \frac{(a_1 + a_2)^2}{(a_1 - a_2)^2} = \left(\frac{5 + 10}{5 - 10}\right)^2 = \frac{9}{1}$
