# Why are there holes in AC Sonometer?

## Why are there holes in AC Sonometer?

This is basically a string instrument which makes the holes similar to an instrument’s sound holes. The effect is to make the audio from the strings louder. If the box were sealed, the vibrations set up by the string could be dampened by the pressure from the air inside.

What is the wooden box of Sonometer hollow?

Sonometer consists of a hollow rectangular wooden box of more than one meter length, with a hook at one end and a pulley at the other end. One end of a string is fixed at the hook and the other end passes over the pulley. A weight hanger is attached to the free end of the string.

### How do you do a Sonometer experiment?

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 is the function of Sonometer board?

Sonometer is basically used to study the relationship between frequency, tension , linear mass density and length of a stretched string. 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.

## 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 material is used for Sonometer wire?

Sonometer wire is made of soft iron for better results.

### What do you understand by 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.

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 is the frequency of Sonometer wire?

100 Hz
The frequency of a sonometer wire is 100 Hz.

Why are there holes in 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. Thus, the sonometer box, the bridges and the string are forced to vibrate with the frequency of the tuning fork.

### How many strings are there on A sonometer?

The sonometer has 5 dierent strings. We list the diameter and linear mass density ofonly one string. 0.022 inch (1.84 g/m)The ends 0.022 inch wire are colored red

How is A sonometer used in the Pasco experiment?

The experiment uses a PASCO Sonometer to measure how normal mode frequencies of metalwires xed at both ends vary with length, mode number, tension, and mass per unit lengthof the wires. A sonometer (or monochord) is a device that holds a single wire under a desiredtension and can detect the normal mode vibrations of a wire. 2 Theory
