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

Subsequently, question is, What is Sonometer frequency?

**Frequency**of a

**sonometer**is given by. f=2l1mMg , where l is the length an m is mass per unit length of the string.

**Frequency**of the

**sonometer**when the mass is immersed in water is. fw=2l1mMg−Vρwg . Here Vρg is the buoyancy force.

Keeping this in consideration, What is the formula for frequency of AC mains by Sonometer?. A low

**alternating current**passed directly through

**sonometer**wire imposes (forces) on it the

**frequency**v (nu) of the

**A.C. main**. Let a loaded stretched soft iron wire have resonant length l

_{1}for the

**main frequency**. Let a tuning fork of

**frequency**V

_{T}have resonant length l

_{2}.

In this manner, What is the frequency of Sonometer wire?

the

**frequency**of a

**sonometer wire**is 100 Hz.

How do you find the frequency of a tuning fork using Sonometer?

The

**sonometer**is tuned first to unison with a standard

**fork**of known

**frequency**and the length of the wire noted. Keeping the tension constant, it is now tuned to the unknown

**fork**by altering the length only.

### 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.

### 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.

### What is the frequency of wire?

The velocity of a traveling wave in a stretched string is determined by the tension and the mass per unit length of the string. for a string of length cm and mass/length = gm/m. For such a string, the fundamental **frequency** would be Hz.

### How the frequency of vibrating wire is affected if the load is fully immersed in the water?

**If the load is fully immersed** in **water**, the tension in the **string** decreases. Hence, the **frequency of vibration** also decreases.

### How do you do a Sonometer experiment?

**Real**

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

### What is the unit of frequency of AC?

**Alternating current** (**ac**) **frequency** is the number of cycles per second in an **ac** sine wave. **Frequency** is the rate at which current changes direction per second. It is measured in hertz (Hz), an international **unit** of measure where 1 hertz is equal to 1 cycle per second.

### What is the frequency of DC?

**DC** is the acronym for **direct current**. **DC** has a **frequency** of zero.

### What is the frequency of AC main?

Complete step by step answer:

It means that in the second **alternating current** changes its direction twice the no of **frequency**. European countries use 50Hz as the **AC** mains.

### What is the unit of frequency?

The number of periods or cycles per second is called **frequency**. The SI **unit** for **frequency** is the hertz (Hz). One hertz is the same as one cycle per second.

### What is the resonance frequency?

**Resonant frequency** is the oscillation of a system at its natural or unforced **resonance**. **Resonance** occurs when a system is able to store and easily transfer energy between different storage modes, such as Kinetic energy or Potential energy as you would find with a simple pendulum.

### What is natural frequency of Sonometer?

At this stage, the length of the wire segment is called the resonating length and it increases with increase in the mass of the suspended weights. When the length 'l' of the **sonometer** wire vibrates with maximum amplitude, the **frequency** of the applied A.C. is equal to the **natural frequency** of the wire.

### What is the formula for fundamental frequency?

waves. The **fundamental frequency** (n = 1) is ν = v/2l.

### How do u find the frequency?

**How to calculate frequency**-
**Determine**the action. Decide what action you want to use to**determine**the**frequency**. ... - Select the length of time. Select the length of time over which you will measure the
**frequency**. ... - Divide the numbers. To
**calculate frequency**, divide the number of times the event occurs by the length of time.

### How do you calculate the fundamental frequency?

If the **frequencies** are all integers and exact multiples of a **fundamental frequency**, you can simply take the greatest common divisor of the **frequencies**. If you're told the **frequencies** are 1760, 2200, and 3080, then the **fundamental frequency** is apparently 440 since that's the greatest common divisor.
