The string wire of the sonometer is a non-magnetic metallic wire like brass or copper. A horse shoe magnet is placed at the middle of the sonometer wire so that the magnetic field is applied perpendicular to the sonometer wire in a horizontal plane.

Besides, Which material wire is used in Sonometer?

Sonometer wire is made of soft iron for better results.

Just so, How does a Sonometer work?. A sonometer consists of a hollow rectangular wooden box to which a uniform wire is attached at one end. The other end of the wire is passed over two horizontal knife edges or bridges and then over a pulley. ... The points at which the wire rests on the knife edges cannot vibrate at all.

Simply so, Why does the string of Sonometer vibrate?

In this experiment a small current, produced by a signal generator, causes the sonometer wire to move up and down due to interaction with the magnetic field of a U-shaped magnet. When the rate of movement due to the current matches the fundamental frequency of the wire, resonance occurs causing noticeable vibration.

What is the nature of the vibration of the Sonometer?

37. What is the nature of vibrations of the sonometer wire when the rider falls ? Answer. The vibrations are resonant vibrations.

What are the applications of Sonometer?

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.

Why are there two holes in the side of the Sonometer box?

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 ...

What types of waves are produced in a Sonometer wire in tuned condition?

The waves produced in a sonometer can be defined as a standing wave.

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 is the principle of resonance?

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.

Why is a Sonometer so called?

Originally Answered: Why sonometer is called sonometer ? sonometer is derived from 2 words - (sono+meter) ; where sono stands for sound. Thus sonometer is an instrument which measure frequency of sound wave. Sonometer is a very simple method for the determination of Frequency of a.c. mains.

Why steel wire is used in Sonometer?

We use a non -magnetic i.e like copper wire in the sonometer so that it doesn't get affected by a permanent shoe-magnet. But if we use an iron or steel wire, it will be attracted by horse-shoe magnet and will not be able to vibrate under the action of electric current and magnetic field.

How are stationary waves produced in Sonometer wire?

What type of waves are produced in sonometer wire? It consists of a hollow wooden box. A string is stretched over the sonometer box with its one end fixed rigidly at one end of the sonometer box and other end is connected to a hanger. ... In string between two rigid supports, transversal stationary waves are produced.

What is the frequency of Sonometer?

The frequency becomes f2 when the mass producing the tension is completely immersed in water and on immersing the mass in a certain liquid, frequency becomes f3.

Which is dangerous AC or DC?

Alternating current (A.C) is five times more dangerous than Direct current (D.C). The frequency of the alternating current is the main reason for this severe effect on the human body. The frequency of 60 cycles is in an extremely harmful range. At this frequency, even a small voltage of 25 volts can kill a person.

Which is better AC or DC?

AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.

Are batteries AC or DC?

Batteries and electronic devices like TVs, computers and DVD players use DC electricity - once an AC current enters a device, it's converted to DC. A typical battery supplies around 1.5 volts of DC.
