A student uses an audio oscillator of adjustable frequency to measure the depth of water well. The student reports hearing two successive resonances at 51.87Hz and 59.85Hz
- How deep is the well?
- How many antinodes are in the standing wave at 51.87Hz?
A glass tube (open at both ends) of length L is positioned near an audio speaker of frequency f = 680Hz. For what values of L will the tube resonate with the speaker?
An air column in a glass tube is open at one end and closed at the other by a movable piston, and a 384Hz tuning fork is held at the open end. Resonance is heard when the piston is at a distance d1 = 22.8cm from the open end and again when it is at a distance d2 = 68.3cm from the open end.
What speed of sound is implied by these data?
Determine the end correction
How far from the open end will the piston be when the next resonance is heard?
The fundamental frequency of an open organ pipe is 261.6Hz. The third resonance of a closed organ pipe has the same frequency. If the speed of sound in air is 340m/s, what is the length of the pipes?
If a human ear canal can be thought of as resembling an organ pipe, closed at one end that resonates at a fundamental frequency of 3000 Hertz. what is the length of the canal?
High frequency sound can be used to produce standing wave vibrations in a wine glass. The glass shatters when the wave is observed to have four nodes and 4 anti nodes equally spaced around the 20.0 cm long glass. If transverse waves moves around the glass at 900m/s, with what frequency will an opera singer to shatter the glass?
In the arrangement, an object of mass m = 5.00kg hangs from a cord around a light pulley. the length of the cord between the point p and the pulley is L = 2.00 meters.
(a) when the vibrator is set to a frequency of 150Hz, a standing wave with 6 Loops is formed. What must be the linear mass density of the cord?
(b) How many Loops if any will result if m is changed to 45.0 kilograms?
A certain vibrating string on a piano has a length of 74 cm and forms a standing wave having two antinodes.
(a) Which harmonic does this wave represent?
(b) Determine the wavelength of this wave
(c) how many nodes are there if 20.0 Newton find the fundamental frequency I'm the next three frequencies that could cause standing wave patterns on the street
A string that is 30 cm long and has a mass per unit length of 9.00 3 1 023 kilograms per meter is stretched to a tension of 20.0 Newton.
