a. Wavelength = 2 * 4m = 8 Meters.
b. Wavelength = V/F1 = 8m.
340/F = 8, F1 = ?.
F1 = Frequency of 1st harmonic.
c. F2 = 2 * F1.
A tube that is open on both ends is 4 meters long. Assuming that the speed of sound is 340m/s, find the following:
a) What is the wavelength of the fundamental standing wave (the first harmonic)
b) What is the frequency of the fundamental wave?
c) What is the frequency of the second harmonic?
