# On which principle does sonometer work?

Asked by: Shannon Knight  |  Last update: 18 June 2021

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.

In respect to this, Which type of waves is produced in Sonometer experiment?

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

Additionally, What is Sonometer and its uses?. 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.

Regarding this, 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.

How do you make a Sonometer?

Real Lab Procedure
1. Place the sonometer on the table.
2. Make sure that the pulley is frictionless. ...
3. Stretch the wire by placing a suitable maximum load on the weight hanger.
4. Move the wooden bridges outward, so that the length of wire between the bridges is maximum.
5. Take a tuning fork of known frequency.

### What are the laws of Sonometer?

Use of Sonometer to Verify the Law of Length:

If the tension in the string and its mass per unit length of wire remains constant, then the frequency of transverse vibration of a stretched string is inversely proportional to the vibrating length. ... Let the lengths corresponding to the frequencies be l1, l2, l3, l4, etc.

### Which material is used for a Sonometer wire?

Sonometer wire is made of soft iron for better results.

### What is the law of length?

Law of Length: The frequency of vibration of a stretched string varies inversely as its resonating length (provided its mass per unit length and tension remain constant.)

### 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 are the laws of vibrating strings?

First law tells that, when the tension and the linear density are constant, the frequency of the vibration is inversely proportional to the length. Second law states that, If the length and linear density are constant, the frequency is directly proportional to the square root of the tension.

### 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.

### 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.

### What happens when the wavelength of a wave increases?

As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter.

### What is the function of bridge in Sonometer?

To keep the wire under tension, a suitable weight is suspended at the free end of the string by a weight hanger. Two movable bridges A and B are provided for the purpose of altering the vibrating length of the wire.

### 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 do you mean by resonating length?

the length at which a string vibrates with same frequency as of the tuning fork or any device having a frequency ( such as AC current) is called resonating length of string.

### Why do we keep frequency constant?

Law of Tension: The fundamental frequency is directly proportional to the square root of the tension. ... This verifies the law of tension. Law of tension (f ∝ √T): The resonance of different tuning forks of different frequencies was observed by varying tension keeping resonating length and wire as constant.

### Why do we keep frequency?

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.
