What is required in a hollow “tube” to resonate?



Asked by: Louis Bigelow

The two most important requirements for resonance are a stable enclosure volume (small or large) and air particles for an instrument that uses air to produce a tone, but solid materials also resonate, just consider a chime or cymbal, and size is still an important factor to consider when choosing a preferred tone.

How do you find the resonance of a tube?





You play a tuning fork here and drop the water. Level. You should have heard there hopefully go the other. Way. There's a moment going each way where the sound is the loudest.

How does a resonance tube work?

As the tines of the tuning fork vibrate at their own natural frequency, they created sound waves that impinge upon the opening of the resonance tube. These impinging sound waves produced by the tuning fork force air inside of the resonance tube to vibrate at the same frequency.

What must be present on each end of an open ended tube in order for a standing wave to be created?

So the basis for drawing the standing wave patterns for air columns is that vibrational antinodes will be present at any open end and vibrational nodes will be present at any closed end.

How are standing waves formed in a tube?

The air in the tube starts to vibrate with the same frequency as your lips or the reed. Resonance increases the amplitude of the vibrations, which can form standing waves in the tube. The length of the air column determines the resonant frequencies.

What causes resonance?





Resonance occurs when the matching vibrations of another object increase the amplitude of an object’s oscillations.

What determines resonant frequency?

In sound applications, a resonant frequency is a natural frequency of vibration determined by the physical parameters of the vibrating object.

Why water is used in resonance tube?

water fills the space that is NOT the air column. It gives you a way to control the exact length of the air column.. so you can listen (or measure) for maximum amplification.. which means you’ve found a resonance point at one of the key points for measuring your sound wavelength.

What is the resonance tube apparatus?

Product Overview. A resonance apparatus is used to locate the resonance positions in air columns. From these resonance positions, it is possible to calculate the speed of sound using the water level (measurements are included on the tube) and the frequency of the tuning fork used.

How does sound travel through a tube?

For example, when a musician blows into a tube such as a flute, the sound produced comes from waves that travel along the length of the tube. Just like other waves, the energy of sound waves increases with the wave amplitude. The loudness or volume of the sound also increases with wave amplitude.



What is needed for the standing wave to occur?

Standing waves are formed by the superposition of two travelling waves of the same frequency (with the same polarisation and the same amplitude) travelling in opposite directions. This is usually achieved by using a travelling wave and its reflection, which will ensure that the frequency is exactly the same.

What condition is necessary for a standing wave?

The condition necessary for formation or a standing wave is that the length of the rope (or the length over which the wave is distributed) must be an integral multiple of the wavelength of the wave.

What are the conditions that must be satisfied to produce a standing wave in a tube open at one end and closed at the other end?

The conditions that must be satisfied in order to produce a standing wave are there must be a node at the closed end of the tube and an antinode at the open end of the tube. Also, the speed of sound must be fixed and the frequency of the tuning fork must also be fixed.



How are standing waves produced?

Standing waves are produced whenever two waves of identical frequency interfere with one another while traveling opposite directions along the same medium. Standing wave patterns are characterized by certain fixed points along the medium which undergo no displacement.

How many nodes and antinodes are formed when the wire vibrates in fundamental mode class 12 physics?

Two nodes and one antinode is formed when the wire vibrates in fundamental mode.

How node and Antinode is formed in transverse wave or stationary wave explain?

When a standing wave pattern is established in a medium, the nodes and the antinodes are always located at the same position along the medium; they are standing still. It is this characteristic that has earned the pattern the name standing wave.

How is resonance created from standing waves?

The term standing wave is often applied to a resonant mode of an extended vibrating object. The resonance is created by constructive interference of two waves which travel in opposite directions in the medium, but the visual effect is that of an entire system moving in simple harmonic motion.



What are conditions for nodes and antinodes?

The particles at these points vibrate with minimum or zero amplitude. The distance between any two successive nodes is λ/2. Thus the distance between two successive antinodes and nodes is equal to λ/2. Therefore antinodes and nodes are equally spaced in a stationary wave.
