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

`12:6:3:5`

B

`1:2:4:3`

C

`4:2:3:1`

D

`6:2:3:4`

Text Solution

Verified by Experts

The correct Answer is:
B
`n_(p)=(v)/(lambda_(p))=(v)/(4l)` `n_(q)=(v)/(lambda_(q))=(v)/(2l)`
`n_(r )=(v)/(lambda_(r ))=(v)/(l)` `n_(s)=(v)/(lambda_(s))=(3v)/(4l)`
