Then press the play button, and see how the incoming wave combines with the reflected wave to form the resulting standing wave. Pause this simulation when you only see one curve. First, you will compute the frequency of this wave, which is the number of cycles per unit time, by using a quantity called the wavelength, which is the distance between two consecutive points that do not repeat themselves. The frequency of the wave is speed of sound, which is equal to 343 m/s, over the wavelength. In particular, f = v/λλ where f is the frequency of the wave, v is the speed of the wave, and λλ is the wavelength of the wave. Compute this frequency by reading out the wavelength, which is denoted by λ, from the simulation and using 343 m/s for the speed of sound.

Then you will find the length of the tube by using the frequency equation for standing waves. First, determine the order of the standing wave. n = 1 would mean that only 1/4 of a wavelength fits in the tube, n = 3 would mean that 3/4 of a wavelength fits in the tube, and n = 5 would mean that 5/4 of a wavelength fits in the tube. Note for tubes that are open on end and are closed at the other, n is always an odd integer. The frequency of a standing wave depends on this value, the length of the tube, and the speed of the wave, which is the speed of sound (343 m/s). In particular, the length of the tube is given by L = n*v/(4fn) where n is the order of the largest wave that fits in the tube, v is the speed of wave (343 m/s), and fn is the frequency of the standing wave of interest that we just computed. Compare the length of the tube that computed with the value given in the simulation.

Hint: L = 5 m and λλ = 3.42 works well.

please show the work for how you compute this
