Solution : 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 called resonance.
Example `:` Let phenomenon is a child on a swing. The swing has a natural freuqency for swinging back and forth.

What is amplitude resonance in physics?
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts.
What is amplitude resonance and velocity resonance?
Velocity resonance is the condition when your system has the highest velocity amplitude and velocity amplitude is the highest velocity your system can achieve during the oscillation.
What is resonance in physics definition?
resonance, in physics, relatively large selective response of an object or a system that vibrates in step or phase, with an externally applied oscillatory force. Resonance was first investigated in acoustical systems such as musical instruments and the human voice.
Why amplitude is high in resonance?
Resonance is created by a periodic force driving a harmonic oscillator at its natural frequency. It is said that the device resonates. The less damping a system has, the greater the amplitude of the near resonance forced oscillations.
How do you find the amplitude of a resonance?
What is resonance in physics class 11 with examples?
A guitar gives sound only by vibration. When we pluck a string in an acoustic guitar, it waves and gives the sound energy into the vacant wooden body of the guitar, making it resonate and amplify the sound.
What is resonance effect explain with example?
Positive Resonance Effect- Positive resonance effect occurs when the groups release electrons to the other molecules by the process of delocalization. The groups are usually denoted by +R or +M. In this process, the molecular electron density increases. For example- -OH, -SH, -OR,-SR.
What is resonance and its conditions?
Resonance is a phenomenon in which the periodic oscillatory force acting on an object has a frequency of vibration same as the natural frequency of the object. In this, the object vibrates with a large amplitude.
What is the formula of amplitude of vibration?
The amplitude of vibration of a particle is given by am=aw2โbw+ca0 Where a0,a,b and c are positive.
What causes resonance?
What causes resonance? Resonance occurs when an item oscillates or vibrates in response to exposure of oscillations at a frequency that matches or is close to matching its resonant frequency. Resonance only ensues when the first object oscillates at the resonant frequency of the second object.
What is resonance frequency?
Resonant frequency is the natural frequency where a medium vibrates at the highest amplitude. Resonant frequency is usually denoted as f0. Resonance is witnessed in objects in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions.
What are types of resonance?
- Mechanical Resonance.
- Acoustic Resonance.
- Electrical Resonance.
- Optical Resonance.
- Orbital Resonance.
- Series Resonance.
- Parallel Resonance.
What is resonance of a wave?
Resonance is the tendency of a system to oscillate with greater amplitude at some frequencies than at others. Frequencies at which the response amplitude is a relative maximum are known as the system’s resonant frequencies, or resonance frequencies.
What is resonance in physics 12th class?
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.
Does amplitude affect resonant frequency?
Resonance is identified by a maximum in amplitude. If amplitude increased above (or below) the resonant frequency then we have not found a maximum in amplitude.
What causes increase in the amplitude?
When there is more disturbance or vibration in a medium, amplitude increases in a wave. Due to more vibration, the wavelength increases lead to the increase in the height of amplitude of a wave.
What is frequency and amplitude in vibration?
Amplitude describes the severity of vibration, and frequency describes the oscillation rate of vibration (how frequently an object vibrates). Together, amplitude and frequency of vibration provide a basis for identifying the root cause of vibration.
What is resonance formula?
The formula of resonant frequency is. f o = 1 2 ฯ L C. Where. fo = resonant frequency in Hz. L = Inductance.
What is maximum amplitude?
The maximum deviation from the average or equilibrium value of any repeatedly changing quantity, such as the position of a vibrating object, pressure, velocity, voltage, current and many others.
How do you find resonance in physics?
Use the formula v = ฮปf to find the resonance frequency of a single continuous wave. The letter “v” stands for the wave velocity, whereas “ฮป” represents the distance of the wavelength. This formula states that the wave velocity equals the distance of the wavelength multiplied by the resonance frequency.
Who discovered resonance?
Resonance is a phenomenon of an increase in the amplitude that occurs when the frequency of the applied force is equal to the natural frequency of the object on which the force acts. Who discovered resonance? Galileo had discovered forced vibration and resonance in the 17th century, though it was misunderstood by him.
What is resonance in RLC circuit?
The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase. The sharp minimum in impedance which occurs is useful in tuning applications.
What is resonance and inductive effect?
The difference between inductive effect and resonance effect is that inductive effect is used for describing the transmission of electrical charges between the atoms whereas resonance effect is used for describing the transmission of electron pairs between the atoms.
What is difference between resonance and mesomeric effect?
The main difference between resonance and mesomeric effect is that resonance occurs due to the interaction between lone electron pairs and bond electron pairs whereas mesomeric effect occurs due to the presence of substituent groups or functional groups.
