MCQ

This question has Statement $1$ and Statement $2.$ Of the four choices given after the Statements, choose the one that best describes the two Statements.

Statement $1:$ In the resonance tube experiment, if the tuning fork is replaced by another identical turning fork but with its arm having been filled, the length of the air column should be increased to obtain resonance again.

Statement $2:$ On filling the arms, the frequency of a tuning fork increases.

A
Statement $1$ is true, Statement $2$ is true,

Statement $2$ is a correct explanation of Statement $1.$
B
Statement $1$ is true, Statement $2$ is false.
✓
Statement $1$ is false, Statement $2$ is true.
D
Statement $1$ is true, Statement $2$ is true,

Statement $2$ is not a correct explanation of Statement $1.$

✓

Answer

Correct option: C.

Statement $1$ is false, Statement $2$ is true.

c
On loading frequency of a tuning fork decreases and on filing frequency increases. If a tuning fork filled length $x,$ then new frequency produced by the tuning fork $n' =n+x$
