The lowest resonant frequency of a closed pipe is the fundamental frequency, so the next resonant frequency that would not resonate in that pipe would be the second harmonic (2 times the fundamental frequency), which would be 400 Hz. Any odd harmonics (3rd, 5th, 7th, etc.) would also not resonate in that closed pipe.
In a resonating pipe that is open at one end and closed at the other, standing waves are formed due to the combination of incident and reflected waves. This creates specific resonant frequencies at which the pipe vibrates strongly. The fundamental frequency for this type of pipe is when the wavelength is four times the length of the pipe.
The wavelength of the sound wave can be calculated using the formula: wavelength = 4 * length. Given the first resonant length is 0.25m, the wavelength for this resonant mode would be 4 * 0.25m = 1m. Similarly, for the next resonant length of 0.75m, the wavelength would be 4 * 0.75m = 3m.
For an empty soda bottle acting as a closed tube, the resonant frequency can be calculated as f = v / (4L), where v is the speed of sound and L is the length of the tube. Assuming room temperature (~ 343 m/s), the resonant frequency for an 18 cm deep bottle would be about 478 Hz. If the bottle is filled one-third full, the effective length of the air column increases, so the resonant frequency would decrease due to the longer effective tube length.
In a tube closed at one end, only odd harmonics are produced. This is because the closed end acts as a node for the pressure wave, leading to a fundamental frequency and odd harmonics of that frequency.

The second harmonic will be 2 x the fundamental; the third harmonic is 3 x the fundamental: 500 Hz, and 750Hz.
To determine the velocity of sound in an open or closed tube, you can use the formula v = f * λ, where v is the velocity of sound, f is the frequency of the sound wave, and λ is the wavelength of the sound wave. In an open tube, you can measure the resonant frequency of the tube and the tube's length to calculate the velocity. In a closed tube, you can use the tube's length and other properties to calculate the velocity.
In general the resonant lengths are 1/4, 3/4, 5/4
The equation used for measuring the speed of a wave is the frequency of the wave times one wavelength. velocity= frequency * wavelength Frequency is defined as how many many cycles occur per second. The unit of measurement used for frequency is Hertz (Hz), because Hertz is equivalent to 1/s. (s=second) The wavelength depends on the type of wave you are dealing with, whether it be an open ended wave, a closed end wave, or just a standard wave. But for calculating speed you just need to remember frequency times wavelength.
The formation of a standing wave requires the interference of a wave traveling in one direction and its reflection. This results in certain points along the medium where the wave's amplitude is always zero (nodes) or maximum (antinodes), creating a stationary pattern. Factors influencing the formation of standing waves include the medium's properties, the frequency and wavelength of the wave, and the boundary conditions of the system.
The velocity of sound in air can be calculated using the formula v = f * λ, where v is the velocity of sound, f is the frequency of the sound wave, and λ is the wavelength. In a resonance tube closed at one end, the first resonance occurs when the length of the tube is one-fourth of the wavelength of the sound wave produced. This information can be used to calculate the velocity of sound in air.
By its very nature, measuring cumulative frequency on either axis of a graph will produce a continuing line on the opposite axis. Therefore, it is impossible to construct a closed frequency polygon when dealing with cumulative frequency.
