In a resonance tube experiment the tube is filled with water upto a height of 17.0 from bottom, it resonates with a given tuning fork. When the water level is raised the next resonance with the same tuning fork occurs at a height of 24.5 cm. If the velocity of sound in air is 
, the tuning fork frequency is
Text Solution
Verified by ExpertsThe correct answer is:
A
A resonance tube is an organ pipe closed at one end. If 
and 
are the first and second resonance lengths with a tuning fork of frequency 
, then the speed of sound in air is given by,
and
