How do you find the frequency of AC mains using Sonometer?

How do you find the frequency of AC mains using Sonometer?

Measure the length of the wire AB between the edges of the two bridges and record it in ‘length decreasing’ column. Bring the two bridges closer and then adjust the length for maximum amplitude by increasing it. Measure the length and record it in length increasing’ column.

How do you calculate frequency in Sonometer?

Formula used: Fundamental frequency of a sonometer $f = \dfrac{1}{2l}\sqrt{\dfrac{T}{\mu}}$.

What are the properties the thread used in AC frequency experiment must have?

Precautions : 1) The thread used in this experiment should be thin with uniform linear density and inextensible. 2) A frictionless pulley should be used so that the tension of the string does not appreciably differ from the weight hanging from its end.

How do you do AC Sonometer experiment?

Real Lab Procedure:

1. Place the sonometer on the table.
2. Attach a weight hanger at the free end of the string which passes over the pulley.
3. Stretch the wire by loading a suitable maximum mass on the weight hanger.
4. The sonometer wire is connected to the secondary of the step down transformer.

What is the frequency of AC mains?

India and most European countries use the electricity which has the frequency of AC mains as 50Hz.

What is an AC Sonometer?

An A.C sonometer is an apparatus by which the transverse vibrations of strings can be studied. It consists of two bridges, near the ends, one horse shoe magnet at the middle and at one end is a pulley.
