Two waves represented by the following equation are travelling in the same medium `y_(1) = 5 sin 2pi (75 t - 0.25 x)` and `y_(2) = 10 sin 2 pi (150 - 0.25 x)`
The intensity ratio of the two waves is …………

A

`1:2`

B

`1 : 4`

C

`1:8`

D

`1:16`

Text Solution

Verified by Experts

`I alpha A^(2) rArr (I_(1))/(I_(2)) = ((A_(1))/(A_(2)))^(2) = (5/(10))^(2) = 1/4`
