Question

State the laws of vibrating strings and

explain how they can be verified using a

sonometer.
​

Answer 1

Answer:

The laws of vibration of strings are easily verified by means of a sonometer. ... The vibrations in the wire are set up by striking a tuning fork of standard frequency with a hammer and placing (l) is adjusted till resonance occurs when the frequency of the tuning fork.

Answer 2

Laws of vibrating strings:

Explanation:

• The rules of vibrating strings are as follows:

        The first vibrating string law is as follows:

• When the tension and linear density remain constant, the frequency of the vibration is inversely proportional to the length, according to the first law.

         The Second Vibrational String Law:

• The frequency is precisely proportional to the square root of the tension if the length and linear density are both constant.

        Using a sonometer to change the law:

• The same length may be made to vibrate in sync with different tuning forks of varying frequencies by altering the tension.
• If l and m are constant, n T. A sonometer is used to verify the law of tension of a vibrating string.
