Considering the length of your resonance tube, what is the lowest frequency tuning fork you could use for this experiment? Show your calculations! If the tubing is 25 cm long and we are at 20°C, we can solve for frequency as follows: Tuning fork Frequency, Hz Length, L, Diameter of Tube, D λ = 4(L + 0.3d) Experimental v = f λ Room Temperature, °C 384 0.065m 0.022m 0.2864m 109.98 20
The frequency of a tuning fork is 401 Hz. Find the length of the shortest organ pipe which will give 6 beats/s with the fork. The velocity of sound in air is 336.8 m/s.
A tuning fork with a frequency of f = 536 Hz is placed near the top of the tube shown below. The water level is lowered so that the length L slowly increases from an initial value of 20.0 cm. Determine the next two values of L that correspond to resonant modes. (Assume that the speed of sound in air is 343 m/s.) shorter length m longer length m
2) A variable length closed end tube has a total length of 110 cm. Assuming the speed of sound in air is 335 m/s, how many resonance points should you hear when the water level is lowered through the full length of the tube if the frequency of the tuning fork is 700 Hz?

Length of Tube A hollow tube is placed in water so that it is open at one end. A tuning fork of frequency 365-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...
