Depedence is disturbances due to two waves on time is shown in the figure, The ratio of their intensities `I_(1)//I_(2)` be :-
.

Options

A. `1:1`
B. `1 : 2`
C. `4 : 1`
D. `16 : 1`

Answer

A

Explanation

`I=(2pi^(2)rhoA^(2)v)/(T^(2))rArr Iprop((A)/(T))^(2)`
`rArr (I_(1))/(I_(2))=((A_(1))/(A_(2))(T_(2))/(T_1))^(2)=((1)/(2)xx(2)/(1))^(2)=1:1`.
