Resonan- I Rcsonm 2 Avibrating tuning fork is held above a column of air as shovel in the diagram above. The reservoir is raised and lowered to change the water level, and thus the length of the column of air. The shortest length of air column that produces a resonance is L1 = 0.25 m, and the next resonance is heard when the air column is L2 = 0.813 m long. The speed of sound in air at 21} 0C is 343 Infs and the speed of sound in water is 1490 Infs a. Calculate the wavelength of the standing sound wave produce by this tuning fork. (2 points) 1}. Calculate the equencv of the tuning fork that produces the standing wave, assuming the air is at 20 0C. {2 points} c. Calculate the wavelength of sound waves produced by this tuning fork in the water. (2 points} {1. the water level is lowered again until a third resonance is heard. Calculate L3 of the air column that produces this third resonance. (2 points) e. the student performing this experiment determines that the temperature of the room is slightly higher than 20 0C. Is the calculation of the 'equencj,r in part (1)} too high, too low, or still correct? (2 points) Justify your
