A closed tube has a frequency n. If its length is doubled and radius is halved its frequency will become

A

halved

B

doubled

C

trebled

D

quadrupled

Text Solution

Verified by Experts

The correct Answer is:
A
`v prop 1//l`
On doubling the length , frequency is halfed
The word 'nearly' in the statement has been used keeping is min 'end correction'.
