The following sets of readings are for a hypothetical Resonance Tube Experiment.The Frequency of the turning forks is f and l is the first resonant length
F(Hz) 200 250 300 350 400 450
l(cm) 33.5 24.0 18.3 14.3 11.3 8.9
1. Obtain an equation for l in terms of f
2. Plot a graph with l as ordinate and f-1( F Whole Number,Raise to de power negative 1(-1) )
3. Use the graph to determine the speed of sound in air and the end correction of the tube
