Question

A sonometer wire is in unison with a tuning fork. Keeping the same tension, the length of

the wire between the bridges is doubled. The tuning fork can be still in resonance with the

wire, provided the wire now vibrates in:​

Answer 1

Answer:

Let the initial length of wire is l.

=2lv=+ ---------------(1)

Now, new length =2l.

let it vibrates in n segments

=n.2(2l)v=+

=n.4lv=2lv

=n=2
