Question

With the water in the tube at the level for the tube length L1 of the first resonance of the first tuning fork: a) would another tuning fork with a frequency lower than that of the first tuning fork produce a resonance? b) Would another tuning fork of some higher frequency produce a resonance? c) If your answer is yes in either case, what would be the frequency of the other fork? (L1 = 18 cm, frequency of first tuning fork = 392 Hz) With the water in the tube at the level for the tube length L1 of the first resonance of the first tuning fork: a) would another tuning fork with a frequency lower than that of the first tuning fork produce a resonance? b) Would another tuning fork of some higher frequency produce a resonance? c) If your answer is yes in either case, what would be the frequency of the other fork?

Explanation / Answer

a) yes

b) no

c)
for part a) f1 = V/2L1

f2 = nV/2L1 = n*f1

n = 2 , 3 , 4.....
