Two waves represented by the following equations are travelling in the same medium
$y_1 = 5 \sin 2 \pi (75t - 0.25x)$ , $y_{2} = 10 \sin 2 \pi (150 t - 0.50 x)$
The intensity ratio $I_1/I_2$ of the two waves is
Text Solution
Verified by ExpertsThe correct answer is:
B
$\frac{I_1}{I_2} = \frac{a_1^2}{a_2^2} \Rightarrow \frac{I_1}{I_2} = \frac{25}{100} = \frac{1}{4}$
