1 Answer. The air enclosed in the sonometer box vibrates when the stem of the vibrating tuning fork is pressed on the top of the sonometer box which increases the intensity of the wave. ... Hence, to increase the area, the sonometer box is hollow from inside.

Just so, Why does a Sonometer box have holes?

The holes in the sonometer box provides a way so that vibrations from the tuning fork (which is excited near the sonometer) is transferred to the inside of the sonometer box. ... Hence holes are provided to the sonometer box to communicate the frequency of vibration of the string to the inside hollow portion of the box ...

Similarly, it is asked, What is the function of wooden box in the Sonometer?. The holes in the sonometer box provides a way so that vibrations from the tuning fork (which is excited near the sonometer) is transferred to the inside of the sonometer box. Thus, the sonometer box, the bridges and the string are forced to vibrate with the frequency of the tuning fork.

Regarding this, What is the principle of Sonometer?

A Sonometer is a device based on the principle of Resonance. It is used to verify the laws of vibration of stretched string and also to determine the frequency of a tuning fork.

Why does the paper rider fall in Sonometer experiment?

When the stem of tuning fork B is touched to the box, the natural frequency of vibration of wire matches the frequency of tuning fork and resonance takes place. Due to this resonance of vibration, amplitude of vibration of wire increases and the paper rider flies off.

What does resonance mean?

1a : the quality or state of being resonant. b(1) : a vibration of large amplitude in a mechanical or electrical system caused by a relatively small periodic stimulus of the same or nearly the same period as the natural vibration period of the system.

What type of waves are produced in Sonometer wire?

Waves produced in sonometer are stationary transverse waves , i e the waves on a string forming rests and troughs.

Why is Sonometer used?

A sonometer is a diagnostic instrument used to measure the tension, frequency or density of vibrations. They are used in medical settings to test both hearing and bone density. ... In audiology, the device is used to test for hearing loss and other disorders of the ear.

How much is a Sonometer?

The sonometer has 5 di erent strings. One inch is equal to 25,400,000 nanometers, so use this simple formula to convert: The length in inches is equal to the nanometers divided by 25,400,000. A sonometer is an apparatus used to study the transverse vibrations of stretched strings.

What forced vibration?

Forced vibration is a type of vibration in which a force is repeatedly applied to a mechanical system. ... Forced vibration is when an alternating force or motion is applied to a mechanical system, for example when a washing machine shakes due to an imbalance.

What Sonometer means?

The sonometer is a long hollow wooden box along the top of which are stretched one or more strings rigidly attached to the box at one end, with provision at the other for changing their tension. If there is just one string, it's known as a monochord.

What is resonance physics?

Resonance describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts.

How do you find the frequency of a Sonometer?

The frequency is calculated using the equation, L = resonating length. T = tension at the string. m = mass/unit length of the wire.

Why is Sonu Metre box hollow from inside?

Why does the wire vibrate in this experiment (AC sonometer)? It vibrates due to electromagnet which is above the iron wire. ... sonometer is derived from 2 words - (sono+meter) ; where sono stands for sound. Thus sonometer is an instrument which measure frequency of sound wave.

Why do we keep frequency constant instead of keeping vibrating length?

Answer. Answer: While verifying the 2nd law of vibrating string experimentally, we vary the tension of the string by attaching weights in increasing magnitude on the hanger due to which the vibrating length at which the paper rider falls off, keeps changing as well and can't be kept as a constant.

What is forced vibration class 12?

Forced vibrations: When a body oscillates/vibrates under the influence of an external periodic force with a frequency different from its natural frequency, the body is said to execute forced vibrations.

What kind of wave is resonance?

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.

Who invented Sonometer?

The sonomètre is a tuning device invented circa 1694 by Étienne Loulié to facilitate the tuning of stringed instruments. Sébastien de Brossard considered this device to be, "one of the finest inventions," of the seventeenth century.

Who invented Monochord?

The monochord was used as a musical teaching tool in the 11th century by Guido of Arezzo (c. 990-1050), the musician who invented the first useful form of musical notation.
