A hollow tube is placed in water so that it is open at one end. A tuning fork of frequency 367-Hz is brought to one end and the length of the tube adjusted so that the sound resonates at its fundamental inside the tube.
If the length of the tube is 24 cm when the tuning fork resonates, what is the temperature in the physics laboratory? (We'll ignore the effects of the tube's diameter)
Hint: Find the speed of sound in m/s
