The displacement nodes of standing waves in a tube are well defined, while the displacement antinodes at the ends can be displaced by a small distance from the actual ends of the tube. So it is best to use the distance between antinodes to to find the wavelength A, Table 2 frequency f wavelength A temperature Te speed v = Af fork 1 fork 2 Compare your experimentally obtained value for the speed of sound with the value obtained from the formula v 2 (331.4 + (0.6/C)Te) m/s
