What is resonance give an example?
When the frequency of an externally applied periodic force on a body is equal to its natural frequency, the body readily begins to vibrate with an increased amplitude. This phenomenon is known as Resonance. Example: 1) Sympathetic vibrations of pendulum. 2) Resonance in radio and TV receiver.
Is one of importance example of resonance?
Acoustic resonance is an important consideration for instrument builders as most acoustic instruments such as the length of tube in a flute, the strings and body of a violin and the shape of a drum membrane use resonators. Acoustic resonance is also important for hearing.
Which is the example of optical resonance?
Optical resonance When 2 mirrors, one partially reflective and other highly reflective are part of a laser, they form an optical resonator. Interferometers and some optical parametric oscillators use optical resonators because it has a large Q factor which suggests less amount of energy loss.
Is a rattle in a car a resonance phenomenon?
A rattle in a car is very often a resonance phenomenon. The car itself vibrates in many pieces, because there are many periodic motions occurring in the car – wheels rotating, pistons moving up and down, valves opening and closing, transmission gears spinning, driveshaft spinning, etc.
How is frequency used in everyday life?
This means that by adjusting the length of the pendulum on the clock, one can change its frequency: if the pendulum length is shortened, the clock will run faster, and if it is lengthened, the clock will run more slowly.
Where is resonance helpful?
Resonance is useful to determine an unknown frequency. Resonance is useful to increase the intensity of sound in musical instruments. Resonance is useful to tune a radio receiver to any desired frequency. Resonance is useful to analyze musical notes.
What is bee resonance?
Electrical resonance is defined as the condition when the magnitude of capacitive reactance becomes equal to that of inductive reactance. As a result of resonance, maximum current flows through the RLC circuit. Given : C=1. 0×10−6 F, L=0. 25 H.
What is resonance Sometimes when a vehicle is driven at a particular speed a rattling sound is heard suggest one way by which the rattling sound could be stopped?
At a particular speed of the vehicle, when the natural frequency of vibration of some parts of the vehicle becomes equal to the frequency of to and fro movement of the piston of its engine, resonance occurs due to which the parts of the vehicle start vibrating violently and a rattling sound is heard.
Why does the body of a bus begin to rattle sometimes when the bus is accelerated?
Why? Answer: At a particular speed, the frequency of the engine of the bus becomes equal to the natural frequency of the body of the bus. The frame of the bus begins to vibrate strongly due to resonance.
What is resonance how is it formed in forced vibration?
An object when forced to vibrate at a certain frequency by an input periodic force, is called forced vibration. Resonance occurs if the object is forced to vibrate at its natural frequency.
Why is a school bus so loud?
Diesel engines are inherently noisy because of the auto-ignition of the initially formed mixture of fuel-vapour and air, which causes rapid rate of pressure rise producing the characteristic noise.
Where is resonance phenomenon used?
The phenomenon of resonance is used in receiving the radio and television programmes.
Where is resonance used?
One use for resonance is to establish a condition of stable frequency in circuits designed to produce AC signals. Usually, a parallel (tank) circuit is used for this purpose, with the capacitor and inductor directly connected together, exchanging energy between each other.
