If two successive overtones of a vibrating string are 280 Hz and 350 Hz, what is the frequency of the fundamental?
If two successive frequencies of standing waves on a string are 225 Hz, and 2.70E2 Hz, what is the fundamental frequency of this string?
In lab, you observe a vibrating string that reaches a resonance at 300 Hz, with 4 antinodes on the string. Which harmonic is in the string? What is the value of the fundamental frequency?
Two successive overtones of a violin string are 1200 Hz and 1520 Hz respectively. What number overtones are they and what would be the frequency of the next highest overtone?
An air-filled pipe is found to have successive harmonics at 800 Hz , 1120 Hz , and 1440 Hz . It is unknown whether harmonics below 800 Hz and above 1440 Hz exist in the pipe. What is the length of the pipe? L= 53.6 cm open-closed pipe Need help with: Identify the correct displacement graph of the 1120 Hz standing wave in the pipe. Note that the closed end of the pipe is on the right.
EXAMPLE 14.8 Harmonics of a Stretched Wire GOAL Calculate string harmonics, relate them to sound, and combine them with tensile stress. PROBLEM (a) Find the frequencies of the fundamental, second, and third harmonics of a steel wire 1.00 m long with a mass per unit length of 2.00 x 10-kg/m and under a tension of 80.0 N. (b) Find the wavelengths of the sound waves created by the vibrating wire for all three modes. Assume the speed of sound in...
Two strings with linear densities of 5 g/m are stretched over pulleys, adjusted to have vibrating lengths of 50 cm, and attached to hanging blocks. The block attached to string 1 has a mass of 20kg and the block attached to string 2 has a mass M. Listeners hear a beat frequency of 2 Hz when string 1 is excited and its fundamental frequency and string 2 at its third harmonic. a) Was is the velocity of the transverse wave...
10. [10 pts] A pipe produces successive harmonics at 300 Hz and 350 Hz. Calculate the length of the pipe and state whether it is closed at one end or not. Assume the speed of sound to be 340 m/s.
A vibrating string 50.0 cm long is under tension of 1N. The result of five successive stroboscopic pictures are shown in the figure below. The stroboscope rate is 5000 flashes per minute and the maximum displacement occurred at flashes 1 and 5 with no other maxima in between. Find the period, frequency, and wavelength for the traveling waves on this string a) b) In what normal mode (harmonic) is the string vibrating c) What is a speed of the traveling...
a) The fundamental frequency of a vibrating system is 450 Hz. If the system is a cylindrical pipe with only one end open, give the lowest frequency (excluding the fundamental) at which a standing wave can occur. b)The fundamental frequency of a vibrating system is 275 Hz. If the system is a cylindrical pipe with only one end open, give the lowest frequency (excluding the fundamental) at which a standing wave can occur.
