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 (20t -0.2 x)` Ratio of intensities `(I_("max"))/(I_("min")) ` will beA. 1B. 9C. 4D. 16

Answer» Correct Answer - B
`a_1=5 , a_2=10`
`rArr l_"max"/l_"min" =((a_1 + a_2 )^2)/((a_1-a_2)^2) =((5+10)/(5-10))^2 = 9/1`
