A vibrating tuning fork is held above a tube filled with water. The first two resonances occur when the water level is lowered by 14.2 cm and 44.2 cm from the top of the tube. If there is a small end correction that adds a small extra length L to the effective length of the air column, calculate the frequency of the tuning fork. Assume the speed of sound to be 330 m/s.
A) 560 Hz
B) 581 Hz
C) 550 Hz
D) 1100 Hz
E) 1120 Hz
