Homework Statement
Q. A hollow metallic tube closed at one end produces resonance with a tuning fork of frequency n at temperature T. The temperature of the tube is increased by dT. If the coefficient of thermal expansion of the tube metal is alpha, the beat frequency will be - (there are 4 option in the attached image)
Homework Equations
Frequency for a tube closed at one end - n=v/(4l),3v/(4l)...
