The vibrations of four air columns are represented in the adjoining figures. The ratio of frequencies `n_(p) : n_(q) : n_(r) : n_(s)` is

A

`12 : 6 : 3 : 4`

B

`4 : 2 : 3 : 1`

C

`1 : 2 : 4 : 3`

D

`1 : 2 : 3 : 4`

Text Solution

Verified by Experts

The correct Answer is:
C
`n_(p)=v/(4 l), n_(q)=v/(2l), n_(r)=2. v/(2l), n_(s)=3. v/(4l)`
`n_(p):n_(q):n_(r):n_(s)=1/4:1/2:1:3/4=1:2:4:3`
