Consider a pipe that is closed at one end. Sketch the standing wave pattern in each of the following situations; showing the regions of high and low air pressure variations (pressure antinodes and pressure nodes). Then formulate equations that relate the wavelength and frequency to the length of the pipe.
A. Tube with one end open ("closed tube"): fundamental
B. Tube with one end open ("closed tube"): first overture (3rd harmonic)
C. Find the ratio of the first overture and fundamental frequencies
D. Tube with both ends open ("open tube"): fundamental
E. Tube with both ends open ("open tube"): first overture (2nd harmonic)
F. Find the ratio between fundamental and first overture frequencies
Pressure Node ---- pressure is maximum or displacement is minimum
Pressure antinode--- pressure is Minimum or displacement is maxmum
Here N--- pressure antinode
A.N---- pressure Node
# At Closed end of pipe Pressure antinode is formed
# At Open end of pipe Pressure Node is formed
# The distance between the two successive Nodes or two successive Antinodes
# The distance between two successive node and antinode
