If the frequencies of two notes in a medium are in the ratio `3 : 5`, then their propagation constant are in the ratio

Options

A. `3 : 5`
B. `5 : 3`
C. `25 : 9`
D. `9 : 25`

Answer

A

Explanation

`k_(1)= (2pi)/(lamda_(1)) and k_(2) = (2pi)/(lamda_(2))`
`(k_(1))/(k_(2)) = (lamda_(2))/(lamda_(1)) = (n_(1))/(n_(2)) = (3)/(5)`
