What is the physical significance of resonance?

In physics , resonance is a phenomenon that occurs when a given system is driven by another vibrating system or external force to oscillate with greater amplitude at a specific preferential frequency .

What is a simple definition of resonance?

In physics, resonance is the tendency of a system to vibrate with increasing amplitudes at some frequencies of excitation. These are known as the system’s resonant frequencies (or resonance frequencies). The resonator may have a fundamental frequency and any number of harmonics.

What is resonance in real life?

Resonance occurs when the frequency of the applied force is equal to one of the natural frequencies of vibration of the forced or driven harmonic oscillator. Swing, Guitar, Pendulum, Bridge and Music system are a few examples of resonance in everyday life.

What is the resonance of the human body?

By testing the response of the human body on a vibrating platform, many researchers found the human whole-body fundamental resonant frequency to be around 5 Hz. However, in recent years, an indirect method has been prosed which appears to increase the resonant frequency to approximately 10 Hz.

What is meant by the term resonance in physics class 12?

If the frequency of the applied vibration is equal to the natural frequency of that body then the body starts vibrating with a very large amplitude. This phenomenon is known as resonance. The frequency at which resonance takes place is called resonant frequency.

What is resonance in physics class 11?

Hint: Resonance occurs when an object with certain frequency is closer to another object whose natural frequency is equal to the frequency of the first object. It occurs when amplitude of an object’s oscillations is increased by the matching vibrations of another object.

What is the meaning of resonance in chemistry?

In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.

What is another word for resonance?

What is another word for resonance?

How can resonance be harmful?

It may cause violent swaying motions and potentially catastrophic failure in improperly constructed structures including bridges, buildings and airplanes. This is a phenomenon known as resonance disaster. Avoiding resonance disasters is a major concern in every building, tower and bridge construction project.

What is human body frequency?

According to the existing research, the natural frequency of a human-standing body is about 7.5 Hz, and the frequency of a sitting posture in the cab is generally 4–6 Hz. The natural frequency of the main body parts is shown in Table 1. The main part of the human body natural frequency.

What is meant by resonance class 10?

When the frequency of an externally applied periodic force an a body is equal to the natural frequency of the body, the body readily begins to vibrate or free to vibrate with an increased amplitude. This phenomenon is known as resonance.

What is resonance in the context of Physics?

In physics the term “resonance” refers to the natural tendency of many objects to vibrate more vigorously at some frequencies than at others. The frequencies at which this occurs are called the object’s “resonance frequencies.”

What is the physical meaning of resonance?

The definition of Resonance in physics is a phenomenon in which an external force or a vibrating system forces another system around it to vibrate with greater amplitude at a specified frequency of operation.

What are some examples of resonance?

Some examples of resonance are a pendulum, a playground swing, a tuning fork and a human voice at a pitch sufficient to shatter glass.

What is the definition of resonance structure?

Definition of the resonance structure. Resonance structures are the multiple Lewis structures of similar energy, the position of nuclei, bonding and the non-bonding pair of electrons that can accurately describe a molecule. They are taken as canonical structures of the hybrid molecules formed by the superimposition of multiple Lewis structures.
